We strive to make the highest quality products possible, and stand behind them with our warranties. However, there are an almost limitless number of vehicles and configurations in the world, and we cannot guarantee that our products will sound or behave ideally on every possible vehicle. While we have went to great lengths to address “exhaust drone” and have received extensive positive feedback, we cannot guarantee that exhaust drone will be completely eliminated or even improved on your vehicle. Although we have had many reports of fuel milage gains and power improvement, results are not typical. We cannot guarantee that using our products will improve your vehicle in any way, including performance, sound, flow, and efficiency. Our statements have not been verified by a third party and are based on feedback from customers and our own experiments.

We are not responsible for any injury resulting from the use or installation of our products.
