400 ex slip on
#1
I know everyone asks this question and people are getting tired of answering it but I want to know what the best slip on muffler would be for low and mid range gains for the 400. Im not concerned with top end.

I think HMF sport series is the way to go for low to mid range power. Here are two links for exhaust system shootouts for the ex.
