Engine performance is heavily influenced by airflow—how efficiently air and fuel enter the combustion chamber and how quickly exhaust gases exit. Unfortunately, factory exhaust systems are often designed with restrictive, quiet components to meet sound and emissions regulations, limiting the vehicle’s true performance potential.

Megan Racing’s cat-back exhaust systems are engineered for enthusiasts who want more out of their vehicle. Designed as a complete bolt-on unit that replaces the restrictive OEM exhaust (while retaining emissions components), this system utilizes smooth mandrel bends and a straight-through glasspack muffler to reduce backpressure, improve horsepower and torque, and deliver a mellow, sporty exhaust tone.

Free-Flow Performance Design: Larger diameter piping with mandrel bends improves exhaust flow, increasing horsepower and throttle response while maintaining drivability.

Durable T-304 Stainless Steel Construction: Built from 100% T-304 stainless steel for corrosion resistance, strength, and long-term performance under extreme conditions.

Straight-Through Glasspack Muffler: Glasspack-style muffler absorbs sound without compromising flow, giving the exhaust a deep, sporty tone without excessive noise.

Direct Bolt-On Fitment: Designed to be a direct factory replacement with no cutting or welding required—perfect for DIY or professional installation.
