  3. Polaris Slingshot Problems and Issues
    Fender from Polaris and exhaust from Slingmods. I called the exhaust makers, Thermal R&D, and Slingmods.com, and both couldn't do anything about this issue or make it right. Slingmods is still selling this without disclosing the incompatibility problem. Your only warning may come from this...

    We were very happy to get one of the early 2.5" Welter Performance dual exhaust setups to test with our DDMWorks supercharged Slingshots and we are pretty happy with the results.
