PSA - You will need a 1/4-20 tap and to replace the two large hose clamps with larger ones. Bought it. Put it on. Does what it says. I'm very happy with it overall. Sounds great on the road! Installation was not hard or easy. The instructions are poorly written and hard to follow. You will need to tap a pre-drilled hole under the hood and it is not easy to do with cheap tools. The two larger hose clamps that go to the rubber coupler are actually smaller than the coupler?!?!
