Part Number: SSXBM1195

Unlock the sound and flow your BMW G80 M3 truly deserves with the Milltek Sport GPF/OPF Bypass Resonated Pipes. Precision engineered in the UK from aerospace grade Type 304 non-magnetic stainless steel, this OPF bypass is designed to fit to OE downpipes and the OE rear system only, delivering a sharper, sportier exhaust note and optimised gasflow while retaining superb build quality and durability.

Expect a deeper, more engaging tone with Milltek’s renowned acoustic development aimed at sporty, crisp sound without unwanted NVH, drone or cabin resonance. If you want your G80 M3 or M3 Competition to sound like a real performance BMW without compromising craftsmanship, this is the upgrade.
