xforce exhaust system

Hence why I sell the 2 1/4" twin into 3" single. No back pressure, as it is a bad thing, and increased exhaust velocity.

Everyone has an opinion, and most people that think they are experts don't like to be told something they haven't figured out for themselves.

And I bet they all mention back pressure.....

actualy not one of them mentioned it until i did

EDIT: do you have results of ur systems's improvments?
