I have...
Surewin Y pipe
muffler deletes
stock everything else...
I think my car sounds better than some cars that have full cat -backs. I don't have a cat-back simply because I haven't heard one in person that sounds better. I would LOVE to change setups mainly for the power increase, but I know once I change out my cats to test pipes, or go to a new mid pipe, I'm going to loose my sound.
I'll post another sound clip of what it sounds like... I love it.
This is what it sounded like before I added the Y pipe.
