procircuit.com is their site.

but if you want to get a good pipe from fmf then then the fatty will be good for you. and they have a couple good silencers that are good but they arent spark arrestors. the titanium 2 is their best. then they have the shorty and powercore 2 silencers.

I like procircuit. I would run a pro pipe on my bike if i could. But sadly I'm stuck with a vintage Dynoport lol. It runs mint. but it is getting a bit dented. Can't change though which exhaust did you end up getting? ~pat

you buy a silencer/spark arrestor. I'm pretty sure you can also just buy the spark arrestor inserts for cheaper. but i think they only work in specific silencer models ~pat

hey guys. my buddy has a older fmf pipe..think its like..year and half old. and hes sellin it to get a newer one for only 200 bucks. was wondering if there is much a difference between that one and a newer one, cuz if not im just gonna buy his for 200.  thx.

also about the yoshi, i want one but my friend said they more for top end performance, and dirt is low end. and that u dont see really any yoshis in dirt racing just super moto. ideas?  

hey guys. so my friend got a fmf pipe that like year and half old, and he sellin it to get a new one, same kind. was wondering if there is much a difference in power, cuz if not ill just buy his for 200, rather than new for 350. thx

also about the yoshi, i want one real bad, but my friend said they more for top end performance and dirt racing is low end, also u dont see hardly any yoshi, if any, in dirt racing mostly supermoto, ideas? thx  

your friend is wrong every factory honda racer has one. the 250's have the dual titanium system and the 450's have the single system from yoshi. even the support honda teams use the yoshi's.

i dont know about the 05 and older though. for the more older hondas i heard the akroprovik and jardine are good.

so you would suggest for my 04 a yoshi? over say a fmf?  

i dont know. i would go with fmf, just because i dont know how well the 04 exhausts are from yoshi.
