2020+ Polaris Slingshot Ceramic Coated Dual Rear Exit "Sport" Tuned Exhaust System by Thermal R&D
Thermal R&D designed a ceramic coated dual rear exit “sport” exhaust system back in 2019 that was compatible with the 2.4 liter GM Ecotec engine that was used in the 2015 through 2019 Slingshot models. That exhaust was and still is wildly popular due to its refined sound, heat blocking ceramic coated finish and for its stylish looks.

Well… for the 2020 model year, Polaris made quite a few changes to the Slingshot. They swapped out the 2.4 liter Ecotec engine for their 2.0 liter Prostar engine, they added some cross bracing down the transmission tunnel and introduced an optional auto-drive transmission, which is explained as a hydraulically actuated manual transmission, that basically drives like an automatic.

So with all these changes in place, the team over at Thermal R&D immediately got to work on creating a new Dual Rear Exit Sport exhaust system for the 2020 and up Slingshot models. Now we knew the guys at Thermal would knock it out of the park, because they exceed our expectations on every product they make, but what we didn’t expect is how insane this 2.0 liter engine was going to sound with the thermal exhaust installed.

Now this is a cat-back exhaust, meaning it still uses the factory exhaust manifold and the factory catalytic converter just like version one did, but this new engine just sounds crazy. The differences from the older 2.4 liter engine vs the 2020 and up 2.0 Prostar engine is quite significant, with the new engine sounding like a Rally Car once opened up. Other than just sounding amazing, this entire exhaust system is ceramic coated from head to tail, including the muffler itself and the custom made Bugatti inspired exhaust tips. The ceramic coating not only drastically reduces heat but protects your exhaust from road salts, oil, gas and corrosion to withstand the test of time. The exhaust utilizes 304 stainless steel with mandrel bends throughout, allowing the air to flow freely until it's composed sound exits the 2 rear exit exhaust tips, producing a sound that's aggressive, without being annoying, and that’s sure to put a smile on your face. We went black on the pipes because the rear end of the Slingshot is black & we really dig that stealthy look. The system runs down the trans tunnel then works its way up the left side of the Slingshot balancing out the rear end, where it then splits into a "Y" pipe that uses factory mounting points to hang those sexy exhaust tips out back, where they should be. Lastly we have created custom "exhaust inserts" that allow you to pop some color for a one of a kind look.

Now we understand that ground clearance on the Slingshot is a frequently discussed topic, especially for those of you running aftermarket coilovers or air suspension, so we ran the exhaust down the trans tunnel so that you don't lose any ground clearance. We also had the exhaust designed with adequate space between the tips so that you can leave your license plate in the stock location.

Installed on our 2024 Slingshot R. No lift available, so like others used ramps and jack stands. Video was spot on. I was able to remove the heatshield from the muffler area exposing the muffler. This made a world of difference in removing the old and installing the new muffler. I didn't have to manipulate past the shield and could see all obstacles. RECOMMEND removing the heatshield all the way. Spring removal is easier than install. Resulted in using the spring removal tool to pry and drop the spring hooks into place. Overall very satisfied and love the new sound.

Best Mod Big difference..
I was on the fence to spend the money or not, my wife complains about the add heat when we are all ready live where the weather cooks all summer in Yuma AZ. It made a huge difference, sound bad aas awesome not like a singer, but not to lound my music is not effected . Best of all no exhaust fumes coming up from down below, also I hated one of my houses has a dirt driveway and the exhaust would blow the dust all over.. Install was a breeze, one pro tip getting the old muffler out , the upper hanger breaker will be tough to slip by the framework, take a Pry bar wedge it thru.. Couple jack stands in your there in no time. around three hours.. Spend the money you will be glad you did….

Exhaust
Exhaust was installed 9/7/2024. The install took approx 3 hours. We had no lift but did raise it up on a ramp and 6 ton jack stands. It was very stable. The install went almost exactly like the video. The hardest part was removing the old muffler, otherwise all was done as the video showed. It has less heat in the passenger area and all noise from exhaust out the rear. A very nice burbling noise. The wife and I are very pleased.

What a difference in look and performance!!!
Love my 22 Slingshot R.. But hated the stock exhaust under the passenger seat.. Love how aggressive it looks and sounds.. The red tips goes perfect with my theme.. I also added Air Intake and the pedal commander and the combination of the three makes this a whole different ride and feel. Not many slings have these dual exhausts installed.. So you will stand out from the group.

Great Exhaust
This exhaust was almost as easy as the video showed. The only thing that took a little time was removing the old muffler. It did not just slid out, it took me about 30 to get it out. After I removed that, the rest was pretty easy. I did not have access to a lift, I jacked up the SS and placed it on jack stands and that was hight enough. No need to take it to a shop to have it installed. If you have any mechanical ability, it’s not a problem. Not only does it make the back look better, the sound is good, and I believe it added a little more pep to the machine. Another great product by Slingmods.
