Polaris Slingshot Front Exit Exhaust System made by Thermal R&D
Introducing the Thermal R&D Front Exit Ceramic Coated Exhaust System for the Polaris Slingshot. This front exit exhaust system is Black Ceramic Coated to insulate heat and protect your exhaust system against road dirt, grime and oils. The guys at Thermal have the secret sauce recipe for muffler sound, as we’ve tested over a dozen front exit exhaust systems over the years from various manufacturers and we’ve yet to hear anything that's as ear pleasing as this front exit setup. These guys specialize in sound quality, its what they’re good at. They create the exhaust and then test the harmonics with computer software and equipment until they virtually eliminate those annoying resonant frequencies that cause both drone and raspy exhaust notes…. and what we’re left with is an exhaust note that products a subtle, but sophisticated sound throughout the entire RPM range that puts a smile on your face every time you drive. If you're looking for a loud and obnoxious front exit exhaust, this is not the system for you. I would recommend this system for those of you that enjoy the sound of a well tuned exhaust system while also being able to hold a conversation in the cockpit.

Just what I wanted.
I have always loved my SS but it didn’t sound like it looked. When showing a friend she asked me to start it so she found hers what it sounds like. I told hear it sounded like a 1964 Ford Falcon.

Now it sounds as good as it looks. It has that low growl that a muscle car has without being too loud. I did install headers when I installed the new ceramic muffler. I figured since I was changing one I might as well change the other.

Ordered this after having issues with 1320 exhaust and factory exhaust baffle. Hopefully 3rd times the charm. I’m running this with 1320 headers and down pipe and it sounds great. Way better than stock but not too loud!

Perfect Sound / Blocks Heat
I switched over to this front exit system because I liked that it was ceramic coated to block heat to the firewall. The sound is louder than the slingmod video showcases.. it has a nice low growl on startup and sounds beefy through the entire rpm range. My girl and I took a 600 mile road trip the day after we installed the thermal system and we loved it. Growl meets ear candy.. perfect balance.

not what i expected..
I installed this on my 2018 SL. The install was a little more difficult than expected, the springs are a pain in the butt to remove and install. The sound is not much different than stock, maybe a little lower tone but not a huge noticeable difference. I do feel a little better performance especially at higher RPM's. If you are looking for a dramatic change in your exhaust sound than I would not recommend this muffler. Quality and fitment seem to good.
