During that year of searching I did a lot of research into aftermarket exhausts because I knew that would be my first modification. I decided on Corsa Extreme after reading and hearing so many good things. Let me say, I'm glad I did! The exhaust is perfect and I couldn't be happier! The looks and sound are unmatched. Tame with no drone at highway speed but VERY aggressive when cruising around town. Exactly what I wanted!

The most popular ones that came to mind was Corsa and Borla I went with the Corsa and I’m more then satisfied. The install was easy and the build quality is top of the line, overall it’s worth the price and wait if you prefer quality
