IRL F97 F98 X3M X4M MaxFlow Race Catted Downpipes
Unlock the full potential of your BMW with the IRL MaxFlow Downpipes, engineered for enthusiasts seeking maximum performance, faster turbo response, and an aggressive exhaust note. Available in both 200 Cell Race and 400 Cell High Flow configurations, these downpipes are manufactured from premium 304 stainless steel and feature precision TIG welding, smooth mandrel bends, CNC-machined flanges, and fully integrated stainless steel heat shields for superior durability and thermal management.
Designed to reduce exhaust backpressure and improve overall exhaust flow, the IRL MaxFlow Downpipes allow the turbochargers to spool faster while increasing horsepower, torque, and throttle response. The integrated heat shields help reduce underhood temperatures, protecting surrounding engine components while maintaining OEM-style fitment and appearance.

Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
