5 of 5 Best Value / Excellent Sound August 27, 2020

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!
