The UFO Vmax Classic Megaphone™ was designed several years ago by Jon Cornell and is 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”.
The Cornell Core™ Exhaust now comes in Show Polished Stainless Steel Slash Cuts, Show Polished Stainless Steel Dual Slash Cuts or Classic Megaphones.
All have Whopping 2.5″ Exits. (Another UFO Exclusive!)
Our pipes are mandrel bent and tig welded for greater flow. They are ceramic coated so they will not rust. The slash cut mufflers are made of show polished 304 stainless steel. All exhaust systems are equipped with with the 2.5 inch Cornell Core™. And yes, you get to keep your center stand and it will clear the oil filter.
If you are a current UFO Exhaust owner and you want to upgrade, no problem! The new UFO mufflers are compatible with our existing systems and are sold as upgrade kits below. The StreetPro™ and Classic Megaphones™ are $195.00 each and the Quadzilla™ mufflers are sold as a set for $495.00.

Jon THANKS THANKS THANKS!
on 23/12 I got the full system exhaust megaphone 2″1/2… Christmas day I installed it on my bike, and … and… unbelievable! the sound it emits is similar to an earthquake; breaks through the sky; to turn on the bike is like a thunder fall to your side;
Simply the best!

Jon, got the megs noonish today.I slapped them on & headed for Lake Tahoe.Just got back & I LOVE the way the bike sounds with the 1.5″ caps. It’s not too loud in my retiree neighborhood or climbing the canyons or going down the interstate 65-80 mph.I’ll let you know what I think of the risers after I put them on. Thanks,Wayne
We installed the Megaphone kit I purchased for my 2004 VMax at our tech day,and we were all very impressed with the quality of the kit. The bends, welds, and fitment are perfect! The system installed very easily with no leaks or other problems. And the sound is incredible, “Pissed off Big Block Chevy”, is the only way to describe it! “Even the Gen 2 guy’s were impressed!”
Thanks for a great exhaust system Jon, “It was great doing business with you”.
