M Performance Exhaust vs Eisenmann Race
I recently had M Performance Exhaust installed, and kind of think it might be a bit quiet but I am not sure since I never heard it from the outside. My next choice will be Eisenmann Race since it was the exhaust I wanted before the M Performance came out. Anyone had experience and/or heard both of them? Let me know what you guys think about both of them!
