Collection: Cat-Back Exhausts
Cat-back exhaust systems are aftermarket components that replace the exhaust system from the catalytic converter to the rear of the vehicle. They typically include the catalytic converter, mid-pipe, muffler, & exhaust tips. Cat-back exhausts are popular upgrades for car enthusiasts seeking to improve the performance & sound of their vehicles. By replacing the stock exhaust components, cat-back systems allow for increased exhaust flow, which can lead to improved engine efficiency & power output. These systems are often designed with larger-diameter piping & less restrictive mufflers, allowing for better airflow & reduced back pressure. Additionally, cat-back exhausts can provide a more aggressive & deeper exhaust note, giving the vehicle a sportier sound. Installation of a cat-back exhaust system typically requires basic hand tools & can be done by experienced DIYers or professional installers. It's important to note that modifying the exhaust system may affect emissions compliance & warranty coverage, so it's recommended to check local regulations & consult with a knowledgeable professional.
