(2015-19) 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!

why do I have to buy the color tips for the R&D thermal exhaust? ( randy k ries, 04/11/2020 7:28 am )
Hello Randy, if you select the "Brushed Silver" Option, there's no additional charge. If you opt for any color other than "Brushed Silver" there is an upcharge as we have to send the tips out to get powder coated for you in the color you selected. Thanks!

Nice Exhaust
Sounds Great, has a deep roar to it. The install video shows certain area of install but don't show the issues you will run into. It comes with no paper instructions so be ready to spend some time on the install.

Looks and Sounds Amazing!!!
The Good—- The exhaust looks and sounds amazing. Pretty easy install even for a novice person. 5 stars on those aspects alone.

The Bad—- One would think the rear exhaust would push fumes back and away from the vehicle, however this design believe it or not brings it right into the cabin, and if my roof is on it is darn near asphyxiating! It is unbearable at time leaving a the occupants with a nauseating headache! I wish R&D for the price could figure out how to remedy this issue, and then it would be a home run product!

Definitely my favorite upgrade so far....
The install wasn’t difficult but wouldn’t say it was simple either...toughest part was removing the stock muffler and reinstalling the springs on Thermal R&D muffler....did the install on 4 jack stands, which didn’t make it any easier....but definitely doable and well worth the hassle....loving the sound and look...

This is an excellent upgrade, Im not sure how much HP it adds but it does feel faster and does produce an awesome sporty sound while driving or idling. After installing exhaust, I silenced my stock system and instead heard the exhaust noise as a was shifting gears. Normally this car attracts a lot of attention but when people see and hear the noise from the definitely get the haterz look. Installation was a pain, it took me about 16 hours throughout 1 week. Installation steps are easy and good to follow from slingmod videos. Recommendation, don't waste your money on the Exhaust Spring Hook Puller. Mine broke. I used instead a pressured pliers and those worked better. I used 2 ramps for the front and 2 jack stands for the rear so my big belly could go through and to have space to install the trans mount. The hardest Another tip, use WD-40 cause all the screws are really tight to take off. Overall, excellent product.
