Cat back?

[HotRodder Glenn]

I am curious, are you guys doing full blown cat back systems, or just changing out the mufflers?

My car is too quiet, need a change.

Thanks,
Glenn

If you just want sound change out the mufflers. If you want a little more performance or plan on future intake mods go for the cat back system of your choice.

Lots of options for sound.
