Performance Overview

It's time to trade your stock muffler for an upgraded and better version. Imagine getting a smooth, deep sound without the vibration or rattling for a fraction of the cost of a full exhaust system replacement. Changing your muffler is a good starter upgrade to improve your vehicle's tone. The strength of this muffler lies in its compact yet free-flowing design. The tubes are constructed from mandrel-bent stainless steel, which is fully MIG-welded for strength and stability and high tolerance to the elements. This exhaust system was created with computer-aided design technology for precise airflow. The same design also allows the product to slot in perfectly with factory fittings. This upgrade complies with the aFe standard of quality and ease of installation. It uses factory hangers, allowing you to directly clamp the muffler without extra hardware, cutting, or modifications. The product is manufactured by aFe in the highest quality possible to ensure long-lasting operation.
