Best AFT MKT Exhaust W/lil to no Jetting

[ojasia]

I Have been Looking at FMF pipes and silencer's, but dont really wanna hassle with all the Re-jetting. Maybe just a little tinkering with the mixture screw I would hope or want. I'm thinking an FmF SST with one of the longer silencer's maybe the powercore 2 or turbinecore 2 ... Has anyone really seen the differences of rich, and lean between the two or does any Aftermarket pipe start to push it to one way maybe more lean I'm thinking with all the extra air moving.

What do you guys think The stock pipe is a lil towards the SST size, and the stock silencer is pretty much a OEM Shorty.

I use(d) a SST on my yz250 and had to rejet, actually it was not too easy to get jetting right on that pipe. The pipe is great, nice overrev I like it. Only reason not running the bike with it is that I'm first need to trash the doma.

Hopefully I can get someone to repair my pipes over here.

What's the goal of the pipe/silencer change?

It important to understand that ANY pipe on ANY engine that doesn't impact the fuel curve isn't likely to impact performance in any significant way either.

If you don't have to change the jetting, then you are just buying jewelry for your bike.
