Dogster Chambers

[LMS]

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.

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

RD350 (A/C) Carbon Steel,  $350 + shipping

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?
