Has anyone used these and if so, what are your thoughts on fit/finish/quality/performance? Google search of their website indicated that these are ~ $450 plus shipping. Shipping from Anaheim to Pittsburgh is 70 bucks, which is reasonable.
Further research states that these are MotogpWerks exhausts sold under this company.
These pipes have been discussed on and off for several years here. I don't believe anyone has run them yet or has any experience with them. As I recall, last time the subject came up I think it was Wade who inquired about availability and was told that they would only build them in a quantity and required a number of advanced purchases to make it worthwhile for them.
Yup, that's what I was told.
They said the same thing to me, but also gave me the option of them being custom built for I think, 100 bucks and hour. No thx.
He is a one man show, and he makes and sells a lot of different things and does not seem to keep stock of anything so its a bit of a strange business model. The stuff that he makes that I have seen has been top quality but it was billet stuff and 4 stroke exhausts.
id rather send my money to the guy in south america, the dogster pipe guy. I actually might buy a set soon.
I have corresponded with him and he is looking for a batch run of 8 to 10 pipes to be profitable, else his labor rate is now $150 per hour with a 6 to 8 month lead time.
Roger Allen at Wicked Motorsports has opened a pipe shop. Might be worth a look for anybody looking for new pipes.
well, the welds look better than they used to.

Just putting this out there again, if anyone is wanting to do the design work for a set of chambers, I will offer the fab/weld work to get them done in exchange.
Come on Mark, you know you want to do a limited edition run of 2stroke world expansion chambers. :clint:

That'd be awesome!
Um, yeah!
pipe making is NOT my forte.
I reached out to Jemco to inquire and they sent me the following:
Brian we build a set of cone expansion chambers with repackable silencers for the Yamaha RD350. The expansion chambers are designed to improve performance
as well as increase lean angle but do require removal of
the center stand.The handmade cone expansion chambers
sell for $795.00 plus tax and shipping. Current build time is 4 weeks. The expansion chambers are made from mild
steel and come in a choice of a raw,polished or high heat
black paint finish. Let us know if you want a set and we will send an invoice and add it to our production schedule.
Thanks for the inquiry
Greg at Jemco
I know these are not SS, but price did not seem to out of line. Any feedback from members who have used these?
i know mark morrow raced and won with jemcos on his rd for years.
also, im not a fan of stainless pipes, they are more prone to work hardening and cracking (at the mounts, etc) eventually vs mild steel. just my preference.

I saw these Jemcos at the One Moto show in Portland a couple of years ago; I think they're pretty sharp looking
I agree, I was thinking these may have been more conventional with a left and a right, not both exiting the bike on the right side. These come in raw, polished or painted. I had a set of JL stainless few years back and liked the look, was concerned with mild steel how these would patina as my current bike with DG's is black, not a fan of painted chambers so most likely will pursue raw or polished, just uncertain as to which one will hold up better
Mild steel holds up well with Mop&Glo or hi temp clear.
My TDR has seen a lot of rain here in Oregon, and the pipes still look good.
I live around Anaheim and asked if Patriot can make pipes for my RD and I got the "go away kid you bother me" impression... :blah:
I got a Jemco made up for my TM/TS400 project. Took about 8 weeks, looks pretty nice, but not necessarily inexpensive.

I take it that is the polished steel finish? I have been looking at the "mop n glo" treatment for the raw steel or the polished, still on the fence regarding which path but all research I have conducted is that the quality of these pipes and "lead time" to order/receive/price seems very reasonable as compared to SpecII's or JL's.

Never seen a head pipe made that way with the straight section. I might try that for the next set of pipes I make.
