MEGAN RACING Mazda RX-8 2003–2008 OE-RS Cat-Back Exhaust System (Stainless Tip)

Overview:
The MEGAN RACING OE-RS Cat-Back Exhaust System for the Mazda RX-8 (2003–2008) is engineered to improve exhaust flow, enhance engine efficiency, and deliver a refined yet sporty exhaust note. Factory exhaust systems are designed with restrictive components to meet noise and emissions regulations, often limiting overall performance. This OE-RS system replaces the factory exhaust from the catalytic converter back while retaining emissions equipment, allowing for improved airflow and throttle response.

Manufactured from 100% T-304 stainless steel, this exhaust system features smooth mandrel-bent piping and a straight-through glasspack muffler to reduce backpressure. The result is improved performance with a balanced exhaust tone that remains suitable for street use while offering a noticeable upgrade over stock. A polished stainless steel exhaust tip provides a clean, OEM-inspired appearance that complements the RX-8’s factory styling.

Designed as a direct bolt-on application, this system installs without modification and offers long-term durability backed by Megan Racing’s proven construction quality.
