These 3″ catless downpipes for the S63-powered F10/F12 M5 and M6 are engineered to deliver maximum performance and reliability. Featuring a machined stainless steel V-band to pipe transition, they ensure a precise, leak-free connection at the turbocharger.
Designed as one of the most effective performance upgrades for the S63 platform, these downpipes can deliver gains of up to 50hp and 60tq when paired with appropriate tuning. By eliminating the restrictive factory catalytic converters, backpressure is significantly reduced, resulting in faster turbo spool, increased power, and a more aggressive exhaust note.
Unlike many alternatives on the market that taper near the turbo, these downpipes maintain a full 3″ diameter throughout nearly the entire length, maximizing exhaust flow and overall efficiency.
To further enhance durability and refinement, a reinforced flex section is incorporated into the design. This eliminates unwanted rattles and reduces NVH (noise, vibration, and harshness), ensuring a more solid and premium driving experience without compromising performance.
