For sale is an Invidia Q300 cat back exhaust. **EDIT** SOLD
This is a GREAT sounding exhaust, and has nearly no cabin drone. Has a nice growl from the outside, sounds mean at WOT, but once the windows are up and you're cruising, the noise is barely there. Great for people who drive alot of highway.
Great clip of how the exhaust sounds with an invidia catted downpipe: https://www.youtube.com/watch?v=_eIwYqFO-Ow
