thinking about an aftermarket exhaust for my 400ex.
think i might get the big gun system. any thoughts?

 

A big gun is good, but it is just to load. go with a white brothers and get a quiet core for it, it gets you down to 96dB. Get that 14t sprocket that you want, it helps so much, in oregon there is this hill called comp. hill, I could only pull second and now I can almost pull 4th! Their only like $6.99 in rocky mountain.[img]i/expressions/face-icon-small-happy.gif[/img]

 

thanks for the info.

 

Id suggest a Duncan Racing Fat Boy 4.Sweeet pipe.My EX had a Big Gun and i liked it but the Fat Boy 4 is nicer. late,zubbeyboy
