Show original supplier description
The Megan Racing NA Type Cat-Back Exhaust System is engineered to enhance the performance and sound of your Lexus IS300 (2001-2005 Naturally Aspirated models). Its straight-through design is optimized to increase horsepower, torque, and throttle response, providing a more aggressive styling and a deep, strong tone. The system features 2.5-inch tubing and a 4.5-inch exhaust tip, which is designed to increase the scavenging effect for maximum performance while complementing the vehicle's exterior styling. A removable double-layer silencer is included, allowing for adjustable sound levels. As a direct bolt-on application, installation is simplified. The product is backed by a 1-year warranty against manufacturer defects. It is important to note that all Megan Racing Exhaust and Suspension products are intended for "closed course and off highway use only." Buyers should verify local laws regarding exhaust modifications to ensure compliance with emissions regulations and smog checks in their state. The manufacturer provides a warranty against defects, but it's advisable to consult local laws before installation.
