Product Details Technical Specs Installation Instructions
 

Bold, full and aggressive exhaust tone isn't limited to vehicles with four wheels. This aftermarket exhaust for Polaris Slingshot 2014-19 models is a bolt-on upgrade that delivers immediate results. The MRT Stinger system has a loud, deep muscle sound to rival any Ford Mustang or Pontiac GTO. By combining premium materials and design with DIY installation, you get one of the most effective Polaris Slingshot performance parts on the aftermarket.

The Right Ammo for Your Slingshot

This Extreme Slingshot Exhaust has a precise design and commitment to quality. It's handcrafted in the U.S. with corrosion-resistant T304 stainless steel. This system includes a 2.5-inch mandrel-bent tube and a straight-through muffler. It is engineered with the best sound to match your Slingshot and provides increased performance from the increased exhaust flow. The Stinger has a simple design and bolts directly to your manifold. The only tools you need for installation are a ratchet wrench and a 3/8-inch deep socket. You don't even need to tune the engine; once the exhaust is secured, start it up and enjoy watching heads turn your way.

The MRT Stinger Extreme exhaust system is designed with a major increase in sound for a definite Hear the Difference and Get Noticed exhaust presence. The muscle car tones are evident even when idling in the driveway or at a traffic light. Stomping on the gas pedal revs things up to an aggressive, almost primal howl. If you prefer a more comfortable ride for your passenger but want the same Extreme sound, check out our side exit Scorpion exhaust (Part #91U120).

5 of 5 Beast of a Sound March 13, 2024

This exhaused is amazing. Deep, Loud sound! They should definitely have better installation instructions. The hardest part was removing the side panels to be able to access the original exhaust and then removing it. Install of the MRT was pretty simple. You will get noticed, neighbors will hate you. It's a beauty of an exhaust!

I did a lot of research on what I wanted on my Slingshot for an updated exhaust.  I was also trying to find one that I was comfortable with for my budget.  I have to say when I landed on your website and saw the video you posted...I was impressed.  Of course everyone has there own say on what sounds good to them.  I had a lot of friends who were just as eager to hear the difference.  You know the one who goes first in your group of friends the rest tend to follow with the same interest.  Everyone was equally impressed when they heard the exhaust installed.  Easy install...the 2 page document could be a little better in details but other than that....I would absolutely recommend this product...I purchased the Stinger

This exhaust system will make your Slingshot LOUD! Which is exactly what I wanted! I have had my exhaust for a little over a year now. MRT installed it for me at their shop and I have had no issues. People notice the sound everywhere I go-  so just know you WILL get noticed.

If you have a Polaris Slingshot, you need to pair it with an MRT exhaust system - period!
