Polaris Slingshot Ceramic Coated Dual Rear Exit "Sport" Tuned Exhaust System by Thermal R&D
Introducing the Thermal R&D "Sport" tuned dual rear exit exhaust system for the Polaris Slingshot. This dual rear exit sport tuned exhaust system from Thermal Research & Development checks all the boxes like its sister product the "Touring" exhaust. It's ceramic coated from top to bottom, which insulates the exhaust heat, vastly reducing cabin foot well and trans tunnel temperatures. The entire system is built from 304 mandrel bent stainless steel and tucks in the trans tunnel so that you don't lose ground clearance. The exhaust system features custom billet aluminum exhaust hangars for the rear end and a trans tunnel mount with polyurethane bushings for the center support along with a center slip joint to allow for vast temperature variations. The custom made Bugatti Chiron inspired exhaust tips exit out the rear of the Slingshot and feature colored inserts for a truly "one of kind" visual statement that's second to none. Cabin smell while driving is virtually non existent unlike other rear exit exhaust systems on the market due to the proprietary design of the Thermal muffler and the fact that the system keeps the stock catalytic converter in place. If you're looking for the creme de la creme of exhaust systems, with a perfectly balanced "drone free" exhaust note throughout the RPM band, that's backed with a Lifetime Warranty... Thermal R&D is the choice for you!

Great product took the overheating problem in the passenger side floorboard away sounds great a little better throttle response had to adjust things a little bit it's pretty tight getting everything to fit down the center tunnel area just took a little tweaking to get everything into place and not rub anything

Best possible upgrade!
Replaced the stock exhaust system with a heavy duty header and the sport exhaust. This really gives the machine the sound it deserves! Expensive upgrade (header, heat shield for header, exhaust system, dealer installation) was about $2,200, but well worth the cost for me!

Six Hours but was worth it
Pros- The exhaust sounds better in person than the video.

I wasn't too bad but wasn't all that easy. Five hours later. Things that helped me was, have someone to help you and is to watch the video as you install it. There is no instructions in the box. We just used jack stands and it worked out for us. Hardest part of the installation was removing the transmission bracket. We had to cut more than an inch off to maneuver it out.

Suggestions- the water pipe clamp should be an adjustable clamp, it don't hold it into position as the intent and purposes.
