DESCRIPTION
Eliminate Harsh Rasp & Deliver Balanced Pure S55 Straight-Six Sound.
The stock unequal length mid piping of BMW F80 M3/F82 M4 creates mismatched exhaust pulses, resulting in a harsh, raspy unwanted noise that ruins the refined straight-six tone of the S55 3.0T twin-turbo engine. Our 70mm SUS304 equal length serpentine midpipe solves this acoustic flaw with a customized wave serpentine bend layout to balance the exhaust path length of both cylinder banks fully. Synchronized exhaust pulses remove the annoying stock rasp, unleashing a clean, crisp, high-pitched exotic racing scream unique to the S55 inline six. Built with full mirror polished 304 stainless steel and smooth mandrel bent tubing, this midpipe cuts exhaust flow restriction, improves throttle response, and delivers consistent power output across all RPM ranges. Precision TIG welded joints and OEM matching flanges enable straightforward bolt-on installation without any cutting or modifications.
