BMW F80 M3 & F82 / F83 M4 (S55) Equal Length Midpipe Performance Exhaust - Vortex

BMW F80 M3 & F82 / F83 M4 (S55) Equal Length Valvetronic Performance Exhaust - Vortex®

The Definitive Sound Correction for the S55 Engine

The BMW S55 engine is a masterpiece of performance, but its unequal-length factory exhaust design is known for creating a "raspy" and unbalanced sound.

Vortex® has engineered the ultimate fix. By precisely balancing the exhaust pulse lengths from both turbochargers, our Equal Length Midpipe transforms the S55's signature rasp into a smooth, deep, and exotic straight-six symphony that finally matches the prestige of the M Power badge.
