Catted Downpipes for BMW M3 G80 / G81, M4 G82 / G83, and M2 G87 (3.0 S58 Engine) - Including Competition Models.
BRONDEX® catted downpipes are equipped with 200-cell high-flow sport catalytic converters, which feature a significantly lower CPSI (Cells Per Square Inch) compared to the stock catalytic converters. This reduced cell density allows exhaust gases to flow more efficiently, decreasing backpressure and improving overall engine performance.
If you’re looking to upgrade your BMW M3 G80 / G81 Touring, BMW M4 G82 / G83, or BMW M2 G87 with BRONDEX® high-flow catted downpipes, you can expect noticeable performance gains, a deeper and more aggressive exhaust tone, and a more responsive driving experience.

Advantages of the BRONDEX® downpipes with High-Flow Sports Catalytic Converters:
-
Increased Power: By reducing backpressure, the engine can produce more power across the RPM range, especially at higher revs.
-
Balanced Sound: The exhaust note is sportier, mature but not excessively loud, making it suitable for daily driving.
- Exact Fitment: BRONDEX® downpipes are precisely engineered to match the factory mounting points of the BMW M3, M4, and M2’s stock exhaust system. This ensures that the installation is straightforward, and no additional brackets or adaptors are needed. The dimensions and angles are designed to mirror the OEM catalysts, ensuring a seamless fit (diameter 3 inch). Since the BRONDEX® downpipes are direct bolt-on, there is no need for cutting, welding, or any irreversible changes to the vehicle. This preserves the integrity of the car and allows the stock downpipes to be reinstalled if needed (OEM fit for models, with and without OPF/ GPF).
-
Compatibility with OEM and Aftermarket Exhausts: The BRONDEX® downpipes are compatible not only with the stock exhaust system but also with many aftermarket exhaust systems. This makes them a flexible choice for those planning further upgrades in the future. Whether you keep the BMW factory exhaust or upgrade to a performance exhaust, the BRONDEX® downpipes will fit seamlessly.
