Turner Motorsport Valved Performance Full Exhaust - E46 M3 - S54

The E46 M3’s high-revving S54 engine deserves an exhaust note that matches its motorsport pedigree. Developed with precision acoustics in mind, this comprehensive exhaust package delivers the ideal blend of high-rpm rasp control, flow performance, and switchable sound volume. Unleashing exotic tones every time you hit the throttle

By pairing our Resonated Equal Length Section 1 with our Valved Stainless Steel Rear Exhaust, this system equalizes exhaust pulse timing to produce a clean, exotic tone. Open the valves via the included Bremman wireless control kit to bypass restrictors for maximum flow on the track, or close them for subtle street cruising. Engineered for a direct fit, this kit comes complete with track-grade HJS hangers and brand-new exhaust hardware to replace worn factory components.
