I've seen quite a few guys with Pro circuit t-4s and ti-4s on their CRF250s
If you;ve got an 06 model onwards you can get them in twin pipe too which looks sick and sounds mint
Bilko runs 2 t-4s if anyone follows FMX

Pro Circuit or FMF.  Avoid carbon pipes. They look good, but are much more expensive and they don't last long.  They will deteriorate and crack without even crashing.

hands down, fmf. so. calf!  

i like fmf i think there the best for a 2 stroke i have it my 2 stroke fmf fatty with a shorty and a turbinecore2 but drd is whats up so look a Dubach Racing Development.com  

I have a Pro Circuit Factory Sound Silencer on my 200EXC,
will this make a difference or does only the header pipe make more power?  

lol funny on page one everyone sayin yoshi and page 2 everyone sayin fmf.

i think ill just go with the fmf factory 4.1  

fmf is a great all around brand. but for 06 or newer i would definitily say yoshi but older then that akroprovic or jardin. but fmf has great exhausts and i say get the whole 4.1 system from fmf but the slip is also good.

yeah i found fmf 4.1 slip on for 350. so once i get a job ill get that, then later get the mega bomb header  

actually this system is really good.
fmf factory 4.1 system w/Titanium Powerbomb Header.

the powerbomb is better then the megabomb

yeah that looks nice. i thought the mega was better...hmm  

ok the mega is better but they offer it seperately but they dont offer it with the full system.

which i dont understand because if it is better then you should be able to get it with the system.

i think you may want to call them or email them about that.

06 Yamaha YZ 250

4 strokes aint nothin but problems

only certain places make you use a spark arrestor like california. and no i dont think the stock one has a spark arrestor.

go to fmfracing.com
mxa said the pro circuit was better for the yz's but when i get my yz i am going to get a pro circuit platinum pipe with with either a 304 or r304 silencer. i dont know which one yet.

kzak if you need a spark arrestor then fmf has the turbinecore series silencers and pro circuit has type 296 and nature friendly silencers.
