Stock Exhaust/Pipe

[Bridgewater]

does anyone have any information on what a 2007 has on it when it comes to the exhaust or pipe?
is it any good and does it even sound good?
ive searched and searched and could not find any info about them or any sounds clips,vid, ect..

also what would be the best slip on out of drd or hmf for a 2007.

A 2007 400EX w/ a stock exhaust I believe puts out 89 decibles. It sounds ok but not the best. And for the second question, get a HMF.

The slip on is excellent, on the other hand there's nothing you can do to your stock system to make it sound better. And sorry....I'm not going to say a way to make your pipe louder.
