Alright, I just down sized from a 450r to a 400ex and im looking for more power!
I mostly trail ride and just screw around with friends drag racing, jumping etc.
Current aftermarket parts
-K&N with outerwears
-FMF powercore slip on
-14t front sprocket - loving this for wheelies
I am getting a slip on exhaust for my 400ex and i am debating between the FMF powercore4 or the FMF Q4. Do you guys think its worth an extra thirty dollars to get the Q4? I also saw the Big Gun eco system but I dont want a poorly built exhaust.
