Check out the look of our superstar muffler installation. It’s not perfect, but it’s tucked-up, secure, and leak-free. The Flowmaster mufflers gave the car a tough new sound and probably released a few extra horsepower. We went with Flowmaster’s two-chamber mufflers (PN 925414) featuring the "side in, center out" exhaust pipe routing configuration. Flowmaster mufflers are constructed of aluminized steel to prevent rusting and have internal metal baffles that won’t blow out years from now.
