Does "muffler" refer to those tailpipe-like things that can be found at most car accessories stores?
If so, is that the thing to change if I'm just looking to get a deep sound, but not looking to alter performance? If it is, any recommendations for a legal one that can achieve above effect? I don't want to lose low-end torque in the process, if that's avoidable. Pls advise! Thanks.
P/S: I searched and have no idea what straight through, etc, are.
