I found them on ebay from a company called Hybers. They are made in China I am guessing but they are perfect fit on the stock exhaust. When I first installed them I used the factory clamps and they held up well. I felt they stuck out a little too far and shortened them a little and welded them on. They were available in black and chrome.I looks like you've got a set of quad tips... Is this a 2.75" stock exhaust? Where did you find quad tips that fit?
