Speedwerx Slip-On Exhaust // 2001-2013 Polaris Sportsman 500

SALE on New Scratch n' Dent Muffler- 

This ATV Slip-On Exhaust System is designed to increase power, add acceleration and throttle response, lose weight and give your quad a new deeper throatier sound.

We try to keep noise levels to a minimum. Most of our slip-on systems will fall at or below 96 decibels.

Carbureted units come with suggested jetting for sea level, summer time riding, if changes are needed.

EFI units come with baseline fuel controller setting if necessary.

However, most systems will require no changes to the stock jetting or EFI mapping. All slip-ons are designed to fit with stock OEM bumpers. Some aftermarket bumpers may affect the sound of the machine. If so we do offer different end caps to route the exhaust outlet more downward so it will not echo off of the bumper.

Silencers have a custom aluminum shell with steel cores and packing material. These cans are 100% rebuild-able with all inner parts being removable. Our steel end caps can also be switched and/or converted over to a custom snorkel outlet set-up very easily.
