There is a guy on ebay selling chambers for 350's, etc. He's out of Brazil, looks to have been building chambers for a while based on his FB feed, etc. Has anyone rolled the dice and bought these? They don't look all that smooth in the pipe fitting dept, but I really don't know much about chambers except what I have read. I'll being buying some chambers in near future, bike now has power pipes on it which aren't my style, per say. I want pipes with silencers on the end, luv the looks. Have read plenty about J&L, spec2, DG, garrets (not making them now), etc. I'm inching toward spec2, f1's, but man are they expensive. I will only be riding this bike around town, city. J&L's look great but have read that they are more of a pipe for the higher rpm range. This dogster guy is selling these pipes for 550 shipped. I have gone back forth with him, just not sure if I want to take the plunge.
Thx much!
J&L - are you talking about Jim Lomas? I have Jim Lomas pipes on my H2 and I think they are the best I've tried for that bike. They have a broad powerband, not top-end oriented.

As Mike already pointed out, I think you're getting brands confused. You mentioned that you have "power pipes", I believe you're referring to J&Rs, which are vintage Orange County-made (and no longer available). JLs are Jim Lomas and made in the Czech Rep (still currently available)
I don't think anyone on this site has tried the Dogster pipes yet. I've been eyeing the aircooled ones for a while. They do look nice, but I haven't seen any dyno data to back up their performance or read any reviews.
i wouldnt risk 800 bucks on a set. for that money, id go with lomas or specII.
anybody tried these?
Patriot?

No, but he's not too far from me. That's Chris Redpath's place. He knows his stuff and has lots of experience (all the way up to the GP & SBK level).
I don't think the prices posted on his site for RD350 or RD400 are current. My understanding is that he builds them on yearly lot basis when he gets enough pre-orders.
Yeah not long ago was a go round here on Patriot about pipes and swingarms.
Found it. https://www.2strokeworld.net/forum/index.php?topic=3852.msg33757#msg33757 -------- https://www.2strokeworld.net/forum/index.php?topic=3838.msg33136#msg33136 ------- https://www.2strokeworld.net/forum/index.php?topic=3836.15
Mark, on ebay, the dogster pipes for aircooled RD's are $350. Shipping typically running around $150. The $400 shipping price is the high quote, they calculate it for you if you message them.
Roger Allen at Wicked has opened up an exhaust shop now. No idea what his prices are though.
Yes, I have JR power pipes and I know what JL's are as well. But I have still read on this site and other that "some" have stated that compared to a few others, lomas pipes with the silencers on the end were/are a pipe more suited for a modified bike that likes to live in the upper rpm range. Is that wrong reading? Also read that the connection at the head pipe isn't all that great either?
Patriot racing: I messaged back and forth with the guy who has that site up and running. He will not sell those pipes at that price unless he has a certain number of orders, which he doesn't. But if I really wanted them, it would be 110/hour to make. Not sure why he just didn't give me a number.. I could see saying yes, then I get a bill for 1200 bucks. No thx.
Then we have, dogster: No dyno, I asked. He said that in Brazil there are a fair amount of RD's. His pipes he states are geared more for the street with a broad power band, but that's just, hear say. But at 550, maybe I'll be the Guinee pig. The prob, if they suck, well I aint shipping them back at that price. Also, I'm a newb. I could install them and think, hey these are frickn great! Then one of you guys that have been wrenching on these bike for years would ride and say, uhhh, these suck. lol, I just don't have any experience is all.

Interesting that these pipes for the 400 are Stainless! And in the listing it states the 350 version are available in SS as well. For $30 I would definitely step up to the SS. No question!
RD400 Stainless Steel, $380 + shipping
https://www.ebay.com/itm/185730929756
RD350 (A/C) Carbon Steel, $350 + shipping
https://www.ebay.com/itm/185730924839
I saw those, but they are for a 400, no idea why the price for the ss ones are much more for the 350's, shipping wise. Also, if you search a lot on ebay, like I do at times, lots of sellers use that weird practice where they sell the same items but change the purchase and shipping prices from post to post. I think that's what he is doing with the ss and carbon steel pipes.
Question for people who have spec2 or JL. If you look, the dogster pipes have indentations for I guess some tabs on the frame etc? Do JL or spec have these? The guy building the dogsters told me he would build them and not indent them if I wanted. I just don't know what and where the indents are for. If I do go this route i could see myself denting them to all hell.
thx
I also checked with Chris at Patriot today - asking about S3 chambers. Same answer, he'll make five sets when we have five buyers. Not likely that I can find four more buyers for S3 pipes. Anyone here?
There's a bikes and coffee meet tomorrow and Tyrone is supposed to ride there with me on his recently completed '78 RD400. I'll ask him what he thinks of the JL pipes.
I'm waiting on an answer from the dogster guy in regard to shipping prices. I'm guessing that if they the charge more for shipping, less for purchase price, maybe they don't hit as hard, tax wise.
I was going to buy JL because let's face it, they are great looking pipes and lots seems to like them. But people also rave about spec2. With the research I did, I was going to get his F1 pipes until he hit me with the 995 price tag. Yikes! JLs can be had for about 120 cheaper if you buy direct.
Then you have the builders in India that are producing some amazing looking pipes, all around the 600 range, shipped. But most of them, if not all, are not setup with paypal accounts. Sketchy.
I met Tyrone and we rode to Bikes & Coffee with two other friends who own CB400F's.
Tyrone has Fukui titanium chambers, not JL. His bike has stage 2 porting, it's very fast! He says it will power wheelie in the first three gears.
Tyrone is on this forum, his username is speedchoppy http://www.2strokeworld.net/forum/index.php?topic=5093.0

Nice find!
running a bit rich down low but they sound good. :bacon:
I went through this a year ago, looking for pipes for my RD350. Milleniums became unavailable (again), I went around and around with Chris at Patriot, Dogster wasn't around yet, there were lovely but unavailable pipes out of the Czech Republic and shiny things from India with unknown performance, quality or actual availability. It came down to price and availability: Spec II were more money and I'd get them someday, while JL were in stock at Economy cycle. Done.
Hot climate aircooled 2T better to be rich at idle.

Are Spec IIs really more than JL pipes these days?

That depends on what pipe you get from spec. F1's are 995, his other version are 200 less. JL's, non ss if bought direct are 800, his other pipe, 680. Both companies offer two different style pipes. Then you have shipping.
garys production costs are probably.. more overall, I cant imagine what his rent is. he is a one man show. currently owning both pipes, i can say the specIIs are damn good as we all know, and the jls are as well, just a preference. the specII's are def racier and tune differently than the lomas pipes.

Not looking to start any fights but a pretty well known east coast builder/tuner called the JL pipes "noisemakers" whenI was in his shop dyno'ing a bike with a friend not too long ago
No problem, i know who hates them. :whistle: I saw no performance decrease running them on my bike vs the f1s that are now on the lightweight. the do need more fuel in the midrange than the specII's did though.
50 rwhp on a 350 with 30mm carbs:
https://youtu.be/fnkrLy8qqmk
A couple of data points.
My RZ came with Spec2 pipes when I bought it in 93 or so and I wouldn't swap them for anything. They run clean and make around 56 at the back wheel with stock motor and carbs.
I ported an aircooled RD a couple of years ago and it came with a seized motor and beautiful shiny Lomas pipes. That one made around 52 at the rear wheel with stock 28mm carbs, and the owner loved it.
Had DG pipes on an RD400G back in Australia that were OK but not inspiring which should come as no surprise to anyone.
I couldn't believe how high DG's are now ($665!!) after seeing ad for them at bottom of Dogster description.
Interesting point about costs.
I have a set of badly dented Jemco pipes here that were mauled by a minivan driver not paying attention. So I need to replace probably 6 cones and the belly part of all 3 and if I buy those at say 80 bucks for a rolled and welded cone, that' adds up to 720 bucks plus there's some assembly required.
So I shall buy a sheet of 20 gauge mild steel, create templates, cut the sheet into parts, roll them and weld them and I am guessing that at a moderate hourly rate that would still cost the owner almost as much as a new set of pipes. At least we can still use the stubs and headers and probably the rear cones and mufflers.
There's a lot of work in making pipes and it isn't cost effective unless you make them buy the truckload. No wonder JEmco and DG and Gary S want a lot more for pipes than they used to.
on a tangent here:
the reality is, most hard and tried and true tuners that have been in the game forever dont like to tune outside their comfort zone, with different pipes, intakes, etc. that' just how most are and therefore, id def take some 'old timer pros' advice with a grain of salt. they like to use what they are familiar with. that's true across -all- hobbies.
As an example, an unnamed tried and true tuner also claims you need a keyway to keep a rotor from slipping on a crankshaft. some TZ's didn't even come with one and its not true. but they wont put a cdi on w out one. Mine sbeen on for almost 2 decades, the only time it slipped was because I used a shitty washer that collapsed.
another one claimed case reeds would -never- work on a kawi triple. which was proven wrong with around 130 RWHP on a dyno shortly thereafter (a bike i've had the privilege of riding).
I'll be honest, if i were looking to build a bike id be willing to try a set out of brazil. if they were total garbage he probably wouldn't last too long selling them. I think DG's sell on nostaligia and ease of availability.
Well, I took one for the team, so to speak. It will take some time for him to build and ship them. Hopefully they arrive, and in one piece.
I had those on my watch list and seen they were purchased.
He responded to my shipping inquiry very quik, the shipping was on the ebay page as $200.00 North America and the response was this.
Hi Jim, how are you?
The shipping to you is USD 115 ok? It takes 14 yo 18 days in travel. And we need some days to manufacture the pipes, as you can see in the ad.
Let me know if you want to order, so i can make an ad to you with the right cost of the shipping for your city.
Thanks for the contact, and regards.

Dogsters? If so like Mark I would give them a try, if I didn't already have so many pipes would order some now.
I will soon order a set of Ktec 2 into 1 pipes just for the look and curiosity.

Pretty much exactly what he said to me. Super nice guy, shipping was 118.
Over a month ago he had the same add up, but it went away. I think it's because he will sell a set, build them, then put another add up on ebay after. He has a website as well, and from what I can tell, it looks like he builds all sorts of pipes for a lot of different 2 strokes. I gather he's also a one man show.
If anyone else is interested, PM him, tell him where you live, and he will PM you back the shipping cost. If you agree he will create another Ebay add for you with the correct shipping. But you might want to wait until I get mine and can at least post some pix of what they look like. My bike is in pieces right now, plus it's colder than he|| here, so I will not be able to actually install them for months. Also, I'm not sure I will be a great person to listen too when I do install them and run them as I'm a serious rookie with these bikes.
this is getting interesting for sure. Im excited to see how they do. always good to have another source if they are decent.

Did you order the mild steel or stainless version? With only $30 difference it seems like an easy decision!

I thought long and hard about that and it came down to looks. Yeah, form over function, per say. I just don't like the looks of SS or chrome. I had a SS muffler on one of my cars and the color it turned made me paint it after that. I think raw steel looks the best. Which brings up another question and that's... what does one coat these with? Read about mop n glo which blows my mind. I mean who actually tried that the first time and then realized it works? Is that the best route? Then there is wd-40, maybe Gibbs, etc. If Mop N Glo is the route, is there a process?
Thanks.
Beat me to it! Was thinking he same thing about the RD350 front fender from Vietnam. One left at a discount on ebay. Sure, just to see... But, I don't need it as my fender is already done.
I would ask what exhaust port timing range they are built for (blowdown is important too but...), reason I mention this is because the RD350 cylinders in India have restricted exhaust ports, possible Brazil has something different from what we are familiar with.
Yamaha had a plant in Brazil producing the RD350LC from 1986-93. I think some restrictions were present for their builds. Even though the model name was different, it was basically a fully faired RZ350.

John are you still making chambers?
I'm not doing anything for sale. I always think about it but never do it. Between Lomas and Gary there is coverage for the market. The selling price is staggering in my mind, I know what manufacturing costs are so I'm surprised there aren't 100 brands to choose from.
Ive run/worked on 2 bikes with pro flo chambers. they were hands down the best ive ever used on an S2 btw. Id buy a set of rd chambers in a minute 100% guaranteed.
Pipes are done. Next step, hopefully they get here and are undented.
nice, these look good.
i asked them, out of curiosity, if they did tzr chambers, they said no.
I cant wait to hear about these things. intriguing.
:popcorn2:
If anyone is interested, choice of cans.
Are you going for #1?
I am possibly going down this path with a set.
Not my bike....
looking forward to your feed back :thumbs:
fyi i reached out to him , he joined the forum. :toot:
Received the pipes today. Took exactly 1 month from the time I ordered them. Not bad considering they had to be built and shipped from south America. They look really good, well packed, no damage in shipping, nice and shiny. I will not be able to install and run them for a few months. But I will start by test fitting the kick stand side as I want to get that in order first. I see a lot of heating, bending, whatever to get the stock side stand to hopefully work. I might even find a different stand and try to make it work. Will snap a pix or two when that occurs.
I also seem to be running into all sorts of things that need fixing. Started polishing the fork tubes only to find out that one leaks, ugh. From what I read, that should be blast trying to get 45-year-old seals out if they are original.
See my $4 seal puller post.
fork seals are easy. use heat 1st.
Being the noob that I am, I have a few questions in regard in installing these. I went to test fit the left side so I could see just what needs to be done with the kick stand, so here goes....
1. These pipes have the flange attached to the chamber (floats), most after mkt pipes I see, the flange attaches to the head, then the pipe slips on and is held in place by springs. With these is it safe to assume I just install exhaust crush gaskets along with some Permatex, etc. and that's that? Man, the inside nuts are hard as hell to get to with these.
2. Attaching silencers: Are these just a compression fit, do I make my own gasket, or lather some Permatex on them first.
3. Wth are these O-rings for?
Thanks again for everyone's input/help.
id use some ultra back of 'the right stuff' to seal the cans.
as far as the flange nuts, these work wonderful:
https://www.ebay.com/itm/264156966757?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=DwhJMRztTaa&sssrc=2047675&ssuid=9DXeqLNdSLW&widget_ver=artemis&media=COPY
when this link expires, look up 8mm vw exhaust nuts brass
they are 11mm hex and will clear any flange with room to spare. :cheers:
Perfect, thx. for those.
Still not sure what those o rings are for. I saw somewhere online that certain cans use them internally when you take one of the ends off, maybe it's that. Took one side off, nope, not there. The other side that attaches to the chamber, spent a little bit of time trying to get that off, wouldn't budge. I asked Dogster, crickets.
By the way, the one I test fitted, it fit perfect. Attaches on the inside of rear foot peg.
The kickstand, no way to hell that's fitting, even with the relocation kit. I bent the living hell out of it, grinded down the relocation kit some so the stand would slide up higher, before it just hung down too much for my tastes. The problem, well, it's so fricken curved that the bike will stand up, but it leans too much now. Ill figure that out later, too cold in garage.
This bike is Nickle and diming me to death. What started out as me fixing the cracked gauge pod, well, it's now a full-blown project. I took the gauge off in nov, first thing I did, heated the cracked side up, bent it, jb welded it into place, and painted it. That turned into me realizing that the speedo was from an xs. Bought a used gauge, ripped both apart, cleaned them to hell, look almost brand new now. Went to put that back on, could not remember for the life of me where the bulbs go. I labeled most, but then realized half were burnt out when I bench tested them. Found a post, ordered some leds.
Im yammering, too much coffee.
The o-rings are for sealing the silencers... At leas that's what it looks like.
What does the inlet side of the silencer look like?
