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”. 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.
UFO Performance Products offers several exhaust options for the 85-07 Yamaha Vmax. To view all the exhaust products available for the Gen 1 Vmax use the tiles below.

Last spring you installed your quadzilla exhaust and a stage 1 jet kit on my 2006 vmax. My buddy and I drove up from Fort Wayne, IN on a chilly Saturday morning and got treated like family. I cannot thank you enough for your hospitality. It was by far the best purchasing experience and best customer service I have ever experienced. The quality of your products along with the care and attention to detail employed in their installation are second to NO ONE. The pipes still look like new, sound awesome and turn heads everywhere I go.
Thanks for great service and superior products.

Ps thank you for letting us look around the shop like that we still talk about how cool of an experience it was
I have the Quadzilla with a stage 7 jet kit and true forced air system. on my 05, My bike is amazine. I love the power and thrust it has, My Friends Hate being behind me, The Quadzilla’s are LOUD but they do sound awsome.. But hey Loud pipes save lifes. And people definitly hear me from blocks away. LOL
This past year, christmas came early for me. My father insisted I pick out exhaust for my 1997 vmax. I choose the entire system with the qualdzilla’s. Little did I know, with this system installed how much authority my bike would have. This sound is totally awesome! Hits like a small block chevy with a .600 cam.. Seriously I ride around town and set car alarms off with it! I plan on making a video of it here soon and putting it on youtube.
Jon! I cant thank you enough! I bought the 4-2 street pro slash cuts and have had them on a week now. Wow is all i can think of to say! I wish i could give you a high five. Thanks again for a great product, and even better service.
Yes! Yes! and YES!
Like Jon said, it’s only exhaust that have made just for a VMAX. I really mean the sound, quality and the POWER for high rews that the 4-2-1 exhaust made for me is awesome!
And the communication with Jon is so pleasant. HIGHLY RECCOMEND!
Let me tell you a little story about Jon Cornell and UFO. I purchased the slashcut exhaust for my 2005 VMax last spring. Jon stepped me through the jetting process last year, and now after the PA winter is finally over, I had a slight problem with my bike because I didn’t drain the gas out of the floats of my carbs, (all my fault). I didn’t know what to do, so I called Jon, and on a Sunday he took time away from his family, (who other than Jon would do that) took the time out and stepped me through a trouble shooting process to fix it! I would, and I do recommend Jon and his UFO company to anyone and everyone!!!!
Tell ya what I was not liking the style of my Kerker tip because of the brushed aluminum look and well it just didnt fit the look I had wanted for my bike. I called Jon and as always not only did he help with what I needed but just good conversation between two guys that have never met other than over the phone. But Jon set me up with a slash cut tip for my kerker set up, hindsight 20/20 I should have bought his in the first place hands down!! OMG the sound is totaly vicious and my harley buddies have to cover their ears to ride with me lol cry babies. They will just have to suck it up and listen to the sound of horsepower and not just the sound valves banging through thier pipes!
Jon brother thank you so much.
I was in the market for a new exhaust for my 04 Gen1, something to make it sound as mean as the bike looks. After doing a lot of research, I found the DragStar 4-1. After reading up on UFO, and talking to Jon, I knew this was the system for me. The exhaust bolted on like a dream and the sound is unmatched!!! I can’t wait for this Alberta winter to dissipate so that I can get out on the road. Thanks for all the help Jon.
Regards,
Josh
To anyone who is thinking about getting these pipes…. STOP THINKING AND DO IT!!! I installed the 4-2 Street- Pro Slash cuts on my `97 and haven’t looked back! It took me about 2 1/2 hours and most of that time was getting the old bulky and heavy stock system off. The sound is unbelievable and well just plain ANGRY!! I have had people literally about falling out of their vehicles rubber necking to see what was making that roar! Let me just say it sounds like you are sitting on top of a Pro stock race car!
I bought the street pro slash cut for my 07 vmax a couple of weeks ago and I’m really happy with it so far. I haven’t had the chance to ride it because I’m waiting for snow to melt but it fit like a glove when installing, and just sounds excellent! It really adds to the look of the bike too I couldn’t be happier, and Jon was really helpful during the process answering any and all questions. I would recommend one of these systems to anyone
Thank you again Jon, by the way the exhaust you sold me a few months ago for my gen 1 vmax is fantastic it draws attention everytime I pull into a bike meet.
Jon, installed exhaust this morning, I have only 1 comment – excellent, really, fell into place in a couple of hours, most of the time was spent thinking! you have to have faith in the fabricator with jobs like that, feeling your pride in the system I was sure it would fall into place – it did. I bet some long hours were spent perfecting it! Putting the center stand back was the hardest part, had to get wife to help!
I could tell you the quality of the welds etc is very good, but I don’t need to, you know that
Will fit carbs when I get the time (& inclination!) will let you know how it goes…
Have a great weekend
