The exhaust flow of an engine has a direct effect on the performance. MONZA Performance Exhaust Systems utilize the right combination of larger than-stock, 16-gauge, mandrel-bent tubing and low back-pressure, high-flow performance mufflers for cooler, smoother engine operation and increased performance. Each system uses corrosion-resistant aluminized steel and features chrome-plated MONZA Exhaust Tips with Resonators. The finish is a durable black paint. Necessary hardware and instructions are included. MONZA Performance Exhaust Systems are designed to replace the original equipment muffler system and, in many cases, attach to the stock catalytic converter.
