Sounds amazing.

The exhaust sounds and looks amazing, I'm a huge fan of it, my car is tuned with extra crackles so pairing it with this exhaust brings me far too much joy, I am glad I spent the money and every time I drive my car it makes me happy. I installed this exhaust myself, I have a few warnings based on my experience. 1: If you aren't changing out the header/cats be warned that you will be in need of two bolts that are splined into the stock exhaust which are not reusable even when removed from the stock exhaust. 2: The rear hangers aren't tight enough to keep the exhaust from sitting low and near the rear bumper. 3: You may need to replace the original metal gaskets.
