Does anybody know what the loudest exhaust system for the 400 is?? What about the one that gives it the most power?? If you know either one please respond. thanks

 

I don't know which is loudest, but as far as which gives the most perfornace I'd have to say the question is wrong. No after market exaust is going to do a whole lot by itself, especially with the anemic jetting of the EX. Boosting the power of your quad has to be approached as a package deal, richer jetting, better intake, less restrictive exaust, etc., all ballanced and working together.

You want performance?? LRD.

 

Yea, I called those guys and asked them if my bike would run on pump gas after they got done with it. The guy says " I don't believe in pump gas ". I figured they were a little too race oriented for me.

Louder isnt always better. It sounds cool at first but after a while it annoys you and the people around you. I have a FMF Power Core IV on my 400EX and it seems to add snappyness at the start but it is VERY loud.

yea,you have a good point.I,m still working on that,TO do,Or not to do.Will update.But I do think they have the exaust down cold.

 

trx430ex, I hear ya. For a while I was thinking of having my quad brored & stroked, the whole nine yards. But it would have cost around 2,800 bucks and would have made it temperamental and unreliable. I like to ride it, not wrench on it. If I ever win the lottery I'll have some totally impractical suicide rocket built for me. 'Til then I'll have to be content with 60+ mph.
