Patriot racing expansion chambers - any good?

[m in sc]

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...

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.
