2006 Pontiac GTO + Kooks Afterburners
I was looking to buy this setup and I wanted to know just how differnet the Kooks Afterburners were from the stock catback. I couldn't find much out there for a comparison video, so I decided to make one for others wondering the same thing. This is a stock 2006 GTO with and without the Kooks afterburners installed. More comparison video to come (acceleration, WOT...)
