how much better does say, a greddy catback exaust system do against a stillen muffler sound and power wise? also whats a cheap way to get some low end power? (automatic)

 

I have heard both the stillen and greddy and to me they are pretty close in volume but the stillen has a deeper tone. Y-pipe or CAI intake is probably what your looking for for low end but may suffer high end compared to other intakes

 

EXHAUST

 

Dang, you got to it before i could...

 

is there any kind of cai you dont have to do cutting to install?
