BMW M4 F82/F83 OPF/GPF bypass downpipes with high-flow sports cats - SSXBM1127

Direct-fit downpipes for BMW M4 F82 Coupe and F83 Convertible (2019-2020 OPF/GPF models only). Not for non-GPF cars, not for G8x, not for any other engine or chassis.

• Milltek Sport SSXBM1127 - full OPF/GPF bypass with high-flow sports catalytic converters
• Mandrel-bent 304 stainless steel; no cutting, no welding, bolts straight onto stock mounts
• Tuned for fast-road and track-day use: sharper throttle response, deeper exhaust note, zero cabin drone
• Not an OEM replacement - built for performance, not compliance paperwork
