BMW S55 F80 F82 F83 F87 Catless Downpipes

PERFORMANCE Series: Essential Power Upgrade for the S55

Unleash the true horsepower potential and raw acoustic signature of your S55 twin-turbo engine with the Performance Series Catless Downpipes. These downpipes are the single most effective bolt-on modification for the BMW F80 M3, F82/F83 M4, and F87 M2 Competition, drastically reducing exhaust back pressure and eliminating the restrictive factory catalytic converters.

• Significant Power Boost: Essential for Stage 2 tuning, resulting in peak gains of 30+ HP and 40+ LB-FT by allowing the twin-turbos to operate far more efficiently.

• Optimal Diameter: Features a precise diameter design to manage the high volume of exhaust gas from the twin S55 turbos without sacrificing velocity.

• Zero Restriction: Catless design ensures the quickest possible path for exhaust gases, crucial for high-boost applications.

• Raw Turbo Spool: Magnifies the distinctive sound of the twin turbochargers and wastegates.

• Deeper Tone: Adds depth and aggression across the entire RPM range, turning heads under heavy acceleration.

• Direct Bolt-On Installation Designed for a seamless installation utilizing factory mounting points and ensuring compatibility with both OEM and most aftermarket catback exhaust systems.
