Active Autowerke BMW M3/M4 F80 F82 F83 S55 Non-Resonated Connecting Pipes - Equal Length Midpipe Exhaust Upgrade (2015+) 11-076NR

Active Autowerke Equal-Length Centre Link Pipes for BMW F8X M3 and M4 - Non-Resonated Mid Section Upgrade

Transform the character of your S55-powered M3 or M4 with Active Autowerke’s equal-length centre link pipes. This non-resonated mid section is engineered to refine the inline-six note, sharpen turbo response and unlock stronger low to mid-range punch. If you want a cleaner, deeper straight-six soundtrack without the buzzy, uneven tone, this is the proven upgrade that enthusiasts choose.

Why this equal-length mid section works

The S55’s two banks exit at different lengths which can create uneven pulse timing once they merge. Active Autowerke’s equal-length approach balances the path before the join, delivering a fuller, smoother note that suits a performance straight-six. With a straight-through, no-resonator design, these link pipes maximise flow and enhance spool-up while keeping the sound purposeful and refined.

Benefits

• Lighter than the OE centre section
• Faster turbo spool and sharper pedal response
• Stronger low-end and mid-range performance
• Equal-length layout reduces the harsh, uneven exhaust character common on the S55
• Non-resonated - clean, aggressive tone without added silencers
• Developed as part of Active Autowerke’s patent pending equal-length mid section system

Real-world results

We have installed these Active Autowerke link pipes on multiple F8X cars and feedback has been excellent. Customers consistently report a deeper, smoother note and noticeably better drivability through the mid-range.
