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!
