Features:
Includes the Cat eliminator tubing, (2) classic megaphone mufflers, and the MaxTuner™ , pre-programed for the TwinStar™ system. Our pricing is below what anyone would spend on a current $1000.00 Gen 1 pipe plus having to buy an $800+ race ECU from Yamaha or a Dynojet Power Commander that starts at $350.00 and up with no mapping. Our product gives the customer guaranteed results! No guess work or another ebay shelf in your garage with products that didn’t offer the performance you expected. They have stainless wool in the baffle core and never need to be rebuilt. Guaranteed for as long as you own the bike.
The TwinStar™ production pipes as well as most of the exhaust systems that UFO Performance Products™ produces, are in a constant state of performance evolution. We rigorously test all of our products using our in house dyno and countless hours of race track testing to provide our customers with proven results. Performance gains, appearance, and the effort required to install the product are always key factors that we evaluate. Each time we make production runs for the consumer market we evaluate the current product and incorporate any changes to the end-product that we find note-worthy. UFO Performance Products™ is dedicated to providing you with the best products on the planet!

Jon,
Wanted to say thanks for a such a great product .
Everything went together perfectly as noted .
I could tell long before completion of installation
That there was allot of thought that went into this design.
The fit and finish is top notch.
The aggressive sound on this TWINSTAR is out of this world.
On the ladder of Performance Exhaust and Service your
Rungs above the rest . It was a pleasure speaking to you
Before my purchase and answering my questions.
Your customer

Hey Jon,
Got the muffs Tuesday. Wow, they’re great! No problem on the finish, that small area you mentioned between the body and bracket isn’t even noticeable on the bike. I made a miniscule adjustment on the left bracket and they’re perfect. Took the bike out for a little putt and got lots of positive comments on the sound/look. It’s a winner. My better half says they’re her favorites for looks and sound, so that’s right from the top. Even had a lady at the gas station come over and look/listen to the bike and her comment was: “Wow, that’s bitchen! They sound great.”
Planning to start the toot on the Thunder Max soon as the gaskets arrive. You done good, Amigo, you done GOOD!
