Edit** Below is my original review. After 6 months the body is completely rusted and some of the innards vibrate at certain low speeds. I just took it off and threw it away. Save money and buy another muffler. This particular series from Magnaflow wasn't as good as I thought it would be. She looks amazing and sounds amazing! Use it with stainless steel clamps and you're done. Minimal moans in the cockpit.
