BMW G80/G82/G87, M3/M4/M2 Equal Length Mid Pipe Z Pipe

Unlock the signature S58 soundtrack with this Equal Length Mid Pipe (Z Pipe) for the BMW G80/G82/G87 M3, M4 & M2 — engineered to transform exhaust tone, improve exhaust pulse balance, and deliver a smoother, more exotic sound profile.

Designed specifically for enthusiasts who want to eliminate the uneven factory exhaust character, this equal length Z pipe configuration restructures exhaust flow to balance both turbo banks before reaching the rear section. The result is a cleaner, higher-quality exhaust note with reduced rasp, improved tone consistency, and a far more aggressive motorsport-inspired sound.

Manufactured from premium mandrel-bent stainless steel and precision TIG welded throughout, this system is built to withstand extreme exhaust temperatures and high-performance driving while maintaining OEM-style fitment and reliability.

Whether paired with factory downpipes or upgraded high-flow systems, this Equal Length Mid Pipe dramatically changes the personality of the S58 engine — producing one of the most desirable exhaust upgrades available for the G80, G82, and G87 platform.

Which OPF Option Do I Need?

European-delivered cars are fitted with a particulate filter (OPF/GPF) in the exhaust. Australian and North American cars are not. The two specifications use different exhaust hardware, so choosing correctly ensures a precise, bolt-on fit.

NON OPF - AU/US SPEC — for vehicles delivered new in Australia, New Zealand, the United States or Canada.

OPF EQUIPPED - EU SPEC — for vehicles delivered new in the European Union or the United Kingdom.

UNSURE - CONTACT US — select this and our team will confirm the correct specification against your VIN before dispatch.

Which Resonator Option Do I Need?

The resonator is an optional in-line silencer built into the Z pipe section. It does not meaningfully restrict flow, but it takes the hard edge off the sound and is the difference between a car that is simply loud and one you can still hold a conversation in at 100km/h.

No - No Resonator Included — the loudest and most aggressive setup, with maximum volume and the sharpest S58 character. Best suited to a car that gets driven hard rather than commuted in.

Yes - Resonator Included — adds the in-line resonator for a cleaner tone with far less drone at cruising speed. Still considerably louder than factory, but much easier to live with on a daily drive or a long trip.

If your car sees regular motorway kilometres, the resonator is the option most owners are happier with long term. If you are unsure, contact us and we will talk it through before you order.

Please Note

Exhaust sound will vary depending on whether factory or aftermarket downpipes and rear exhaust systems are installed. Professional installation is recommended.
