Polaris Slingshot Ceramic Coated Dual Rear Exit Exhaust System by Thermal R&D
Every once in a great while a product is released for the Polaris Slingshot that absolutely blows our minds. This dual rear exit touring exhaust system from Thermal Research & Development is one of them! This is the first exhaust system for the Polaris Slingshot that checks all the boxes. It's ceramic coated from top to bottom, which insulates the exhaust heat, vastly reducing cabin foot well and trans tunnel temperatures, making it the most comfortable rear exit exhaust system we've tested to date. 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. Most importantly, the tips run low to the ground and shoot out of both the left and right corners of the vehicle, making this the first dual exit exhaust system that is compatible with all of our rear fenders and luggage systems. It's also the first rear exit exhaust system that had zero emissions smell in the cabin. 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!

Do you need a 1320 header with this exhaust system? Also with this exhaust system does it change the sound of the slingshot? Looking for a deeper sound and hopefully less heat on the passenger side. ( Doug Kantor, 01/20/2019 7:46 pm )

Hello Doug, this system is a "cat back" system and can be run as is. You do however have the option to pair it with our aftermarket header and cat delete pipe if you'd like. It's the best sounding exhaust system we've heard so far for the Slingshot. Nice low rumble with zero emissions smell in the cabin due to the cat back configuration. It's ceramic coated head to tail.. this cuts the exhaust temperature by 50% in comparison to non-coated stainless steel. This is the only ceramic coated rear-exit exhaust system on the market at this time. Please let me know if you have further questions. Thanks!

Does this syestem replace factory muffler and catalytic converter ( Eric Retter, 01/20/2019 4:39 pm )
Hello Eric, yes and no. It comes with a new triple chamber ceramic coated muffler, but the system is cat back to prevent cabin fumes smell, which has been a huge complaint with other exhaust systems on the market. You can however run our aftermarket cat delete pipe and header if you'd like. Thanks for the inquiry.

sounds great
this sounds great after it is on. It's not as easy as the video shows. Could not get 2 of the springs on. Will try to get them on tomorrow? There is no reason this doesn't have written instructions included with it in this day and age. Had to cut a small bit of the "Y" pipe off to get it to fit. Heat shield does not work with muffler. Those that say they could reuse it must have had to really bend the crap out of it. Was it worth it? yes, so fare. Haven't had it on but, for a few days. A little expensive. Time will tell how happy I will be.

SlingMods Response:
Hello Gm, thanks for the review. The "Y" pipe does not have to be cut... this system is jigged to fit without any modification. The written instructions would be long and arduous so we did a video instead to visually walk you through the process from start to finish.

Great improvement
Exactly what I was looking for. Nice throaty sound but not overbearing. Very well hidden under the slingshot with very little worry of bottoming out. The use of a hoist is highly recommended for the install. Could be very tricky laying on your back. Really nice fit and finish. Looks like it came stalk. I'm still doing some tweeting on the exhaust tips to get them to hang evenly.

Thermal R&D Ceramic Coated Dual Rear Exit Touring Exhaust
The wait was worth the product. My anticipation to hear the sound from my new exhaust was well worth the wait. The sounds is unique and strong and I feel a slight increase in horsepower. Though the price is a little high I am really enjoying the product.

Slingshot duel, rear exit exhaust
I can't believe how great this exhaust sounds! I would recommend this exhaust to all Slingshot owners! Also getting this great sound out the rear of the Slingshot is a big improvement!

Does come with a parts list or installation instructions, other than SlingMods video.
