Active Autowerke BMW F80 F82 Exhaust Mid-Pipe - Non-resonated for M3 and M4
Looking for the best BMW M3 M4 mid pipe upgrade for more power, better sound and real performance gains on your F80 M3 or F82 M4? The Active Autowerke Non-resonated Mid-Pipe is a proven F8X exhaust centre section that frees up flow, sharpens response and delivers a deeper, throatier exhaust note without the thin, raspy weed-eater sound many owners dislike.
Active Autowerke has engineered BMW performance parts for over 30 years. This single 3.5 inch oval mid pipe was designed to remove the highly restrictive nature of the factory F8X mid section. The oval profile maintains ground clearance while maximising exhaust gas velocity and reducing back pressure for genuine seat-of-the-pants performance on your BMW M3 or M4.

How it improves sound and flow
The factory F8X M3 M4 exhaust uses silencers and a small crossover that dampen noise yet create restriction and accentuate an out-of-sync turbo sound. Active Autowerke’s single mid pipe equalises pulses to clean up the tone, unlocks flow for power, and uses an oval 3.5 inch tube to maintain ground clearance. The result is a deeper, more refined M-car soundtrack with performance to match.
