have you tried a glass pack.....i know its unconventional but i did it and the car has a really unique 4 cylinder sound...deep and raspy...sounds mean. and there like 32 at checkers.
hey every one. i got a 07 chevy cobalt. put a glass pack on it about a year ago and now i have a ratteling sound comming from the exhaust and it sounds like the pipe is loose but cant figure it out. but what really bothers me is i also have a deeper sound comming from the front of the car...
