Upgrading your Polaris ACE exhaust system isn't just about making your ride sound great. Most riders choose to upgrade their exhausts to boost performance. Whether it's choosing a slip-on exhaust, muffler, or a completely new full exhaust, an aftermarket exhaust can make a noticeable difference in power. Additionally, some Polaris ACE owners, particularly those with the edition, install aftermarket exhausts because of a recall on the exhaust header pipes. The recall caused the exhaust to become extremely hot and damaged nearby components. Many riders have attempted to control the heat by wrapping their exhausts with insulation or applying NASCAR-style fireproofing. With aftermarket exhausts, not only can you fix the heat issue but also improve your machine's performance.
