Polaris Slingshot Dual Exhaust System for the Polaris Slingshot by Welter Performance
Finally, we have a rear exit exhaust system for the Polaris Slingshot. Not only is it a rear exit system, but it's a dual rear exit offered in your choice of Carbon Fiber or Black Silencers to match your Slingshot's color profile. There are many benefits to the Welter Performance WP Dual rear exit exhaust in comparison to the traditional front exit exhaust systems we've seen for the Polaris Slingshot so far.

Please note that running a taller windshield (3"+ and 5"+) may cause some fume smell in the cabin.

Benefits of the WP Dual Rear Exit Exhaust System from Welter Performance

  • Drastically reduces firewall heat by allowing hot exhaust gases to flow behind the Slingshot
  • Looks absolutely stunning and in our opinion how the Slingshot should have always looked
  • Easy on the ears because the sound exits behind the Slingshot
  • Reduces emissions smell because of the rear exit design
Features of the WP Dual Rear Exit Exhaust System from Welter Performance
  • Mandrel bent 2" piping for smooth exhaust flow
  • Brushed finish Stainless Steel Rear Section
  • Compatible with Stock Manifold, 1320 Header & Alpha Header
  • Removable DB Inserts for Mild or Wild Exhaust Note
  • CNC Machined Flange
  • Header Wrapped Aluminized Steel through transmission tunnel
  • Mounting hardware included
  • Patent Pending

Will this dual exhaust system fit a 2018 SL with the optional polaris rear fender? ( Bobby, 01/12/2018 8:59 am )
Hey Bobby,

This exhaust would not with the new Optional Fender from Polaris unfortunately. Please let us know if you have any further questions or concerns. ( SlingMods )
Hi I am planning on installing a supercharger in my 2016.5 SS. Will this exhaust work well with it? ( Steve, 11/05/2016 5:33 pm )

Hello Steve, if you plan on pairing the Welter with your Supercharger Kit on your 2016.5 Slingshot, you'll need this version of the Welter exhaust:

Thanks for the inquiry.. please let me know if you need additional assistance!

If I have a header and this exhaust do I need to put a performance chip in, will it make the engine run lean if I don't. Do you recommend certain chip? ( Joe Whitlow, 09/11/2016 5:39 am )

Hello Joe, there is no "power chip" available for the Slingshot unfortunately. We do recommend the tune from MefiBurn to maximize power once these mods are complete.You will simply enter in which mods you've done and physically mail in your ECM to their location. They'll reflash your ECM with the proper tune and ship the ECM back to your location.

Here is a link to the product: http://www.slingmods.com/polaris-slingshot-ecm-reflash-tune-mefiburn-obd-diagnostics?search=mefi

Thanks!

I have the Assault Industries rear fender. Will the Dual Exhaust system work with that fender? If Not, will one of the single exhaust systems work. ( Nick Chelenza, 08/30/2016 6:48 pm )
Hello Nick, yes.. the MFG has confirmed fitment with the Assault Rear Fender at the Welter Dual Exhaust System. Gonna look awesome with that combo!
( SlingMods )
I really like my rock guard and the install says to remove it. It there any way I can keep my rock guard with this exhaust? ( Jerry, 08/25/2016 5:46 pm )
Hello Jerry, I like the rock guards too.. but unfortunately not. That area is needed for the Welter exhaust system.

Welter Performance "Dual" Series Rear Exit Exhaust System for the Polaris Slingshot
This product was easy to install and it looks and sounds great! The DB inserts helps with getting the optimal sound you are looking for.

Wow, what a difference in performance!
I ordered this system together with the header, and one of the best mods for the machine. I took my time and installed if from the video, had to tweak it a bit, to keep pipes away
from plastic, and added additional heat shield placements accordingly. You get the engine rpms in the right power bands and this thing is that much more fun......
Thanks to you guys for doing your homework.

This was fine Welter was very nice and helpful trying to figure out what that heat wrap thing was all about.

Welter Performance "Dual" Series Rear Exit Exhaust System for the Polaris Slingshot
The rear dual exhaust system I purchased made my slingshot sound the way it looks. It did increase cabin noise somewhat but not enough for me to install the inserts. The noise level easily passed the wife test it actually put a smile on her face. So if you want your SS to sound like it looks then buy all means put the Welter Performance dual exhaust system on.
