another exhaust thread

i have a chance at an FMF powerbomb header and t-4 combo for my stock 400ex in a trade for an xbox 360. plus a rev box i dont know how big the gains would be for the box. if anyone has had a similar or same setup could you post some feedback on it. does anyone have an idea of how loud these pipes are and the power gains. thanks

Well in the 4 stroke world FMF isn't all that good. But guess what the exhaust wont win the race cause 1hp more or less means nothing! I say trade that exhaust new plus rev box is much more than the Xbox costed.

ive heard alot of negative things about FMF but ive heard pro circuit is pretty decent. im just looking at it as an improvement over stock. plus i dont like the sound of my 400ex stock that much :ermm:
