We should all just meet up so everyone can listen to them all. Maybe we are all just too old for exhaust because I sure think my AA w/ stock X-pipe is just too loud. And the problem is I want more power so I need to get rid of those cats. Akrapovic may be the only solution.
Get the akra evo!! Very noticeable power gain and great sound
