[JWALK]

I have a 2002 Honda 400ex, and i am starting to beef it up a little, i bored it out and go a new piston and was just wondering what the best exhaust is for it?

HMF makes nice exhausts try them.

hmf makes some really nice exhaust system for not that much money, i run the curtis sparks X4 full system, its pretty loud but makes awesome low to middle torq

HMF are really nice. Also look at Yoshimura. The RS-3 is great and isn't too pricey and gives great gains IMO.:cool:

I ahve nothing bad to say about my Curtis Sparks x-6.;)

I just bought my full hmf w/out the quiet core and yes it does have a deep sound.. more like a deep growl.. it is very powerful through the gears.. and right now u can buy a brand new one for 337$
