Several years ago, Jon Cornell designed the world's most powerful exhaust for the Yamaha Vmax. Since then, many have tried to copy the design but have yet to duplicate it. Do not be fooled by these imitations, the UFO exhaust, with the Cornell Core, is the original!

UFO would like to thank one of our old pals "Mario" for helping us promote our exhaust. "Mario" recently removed the Kerker exhaust he always promoted, and sold to many of you, on the internet, at prices that were a "steal". It seems after getting his ass kicked by his buddy "Bill", who has the original UFO 4/2 exhaust for the past year, he has now installed a cheap imitation of our product. With Dyno results like the ones shown at the bottom of the page, we would like to offer thanks for helping us prove that we have the superior exhaust on the planet. The pipe he promotes is a design stolen from UFO, produced by a fly-by-night company interested only in your dollar, not your performance. The material will rust out. The coating will peel off and the pipes will crack. Our pipes, on the other hand, are made from the highest quality materials available with a ceramic fiberglass packing that won't burn out. They are also the only VMAX pipes in the world that have 2.5 inch exits with show quality polished 304 stainless steel slash cut mufflers or classic style megaphones, offering the highest level of performance. These pipes have the lowest, deepest note to ever billow out of a VMAX engine. Remember, good pipes aren't cheap, and cheap pipes aren't good! Below are the Dyno runs comparing the UFO pipes to a Kerker in a sorry state of tune by it's owner and the "Wannabee" 4/2 pipes now on Mario's bike, as well as a handfull of the sorry souls. We at UFO give you All the information available on product comparisons. Facts... proven on the Dyno, not opinions of misguided theives out to take your money and offer no support . You can either ride with "Bill" or follow like "Mario".

Don't just listen to us, hear what our customers are saying...

(Note the 17 hp difference in our favor!)

Above Right: UFO 4/2 versus the poorly done knock off exhaust. 117.6 hp for UFO and aproximately 107 hp for the competition. You do the math!
