BMW S63R 4PC Catless Downpipes - F90 M5 / F92 M8

Unlock the full potential of your S63R-powered BMW with the Agency Performance Catless Downpipes, designed for the F90 M5 and F92 M8. By replacing the restrictive factory catalytic converters in both the primary and secondary sections, these downpipes maximize exhaust flow, reduce backpressure, and allow the 4.4L twin-turbo V8 to breathe as it should.

Crafted from high-grade T304 stainless steel, these downpipes are built for strength, heat resistance, and long-lasting performance. The catless design drastically improves turbo spool, enhances throttle response, and delivers a raw, aggressive exhaust note that amplifies the character of the S63R engine. When paired with tuning, expect significant horsepower and torque gains along with sharper driving dynamics.

Perfect for enthusiasts looking for maximum performance, the S63R Catless Downpipes are a must-have upgrade for both street builds and track-focused machines.
