IRL MaxFlow Race Downpipes for BMW F90 M5 & M8
Unleash the full performance of your BMW F90 M5 and M8 with the IRL MaxFlow Race Downpipes, engineered to maximize exhaust flow, improve turbocharger efficiency, and deliver the aggressive sound the S63 twin-turbo V8 deserves. By significantly reducing exhaust backpressure, the IRL MaxFlow Race Downpipes provide faster turbo spool, sharper throttle response, and increased horsepower and torque throughout the powerband.
Manufactured from premium 304 stainless steel, each downpipe features precision TIG welds, smooth mandrel bends, and CNC-machined flanges to ensure exceptional durability, leak-free performance, and OEM-quality fitment. Designed as a direct bolt-on replacement for the factory downpipes, installation requires no permanent modifications.
The IRL MaxFlow Race Downpipes transform both the performance and character of the F90 M5 and M8, producing a deeper, more aggressive exhaust note while allowing the S63 engine to breathe as intended. Whether you’re running a factory tune or a high-performance calibration, these downpipes provide the airflow needed to support substantially higher power levels.
