BMW G80/G82/G87, M3/M4/M2 Stainless Steel Valved Z Pipe Catback Exhaust

A complete stainless valved exhaust for the BMW G80 M3, G82 M4 and G87 M2 - from the downpipes back, with an equal-length Z pipe mid section, a valved rear muffler and quad tips, supplied with the wireless valve remote kit.

Built around the twin-turbocharged S58, this system replaces the full factory exhaust behind the downpipes. The equal-length Z pipe balances flow from both turbochargers before it reaches the muffler, which is what gives the S58 a smoother, fuller note rather than the raspy tone of an unequal system.

Manufactured from mandrel-bent stainless steel with precision TIG welding throughout, finished with a laser-etched muffler and supplied complete with the valve remote kit and all hardware.

Key Features

Equal-Length Z Pipe Mid Section

Both turbochargers feed matched-length pipes, balancing pulses for a smoother, fuller exhaust note and consistent flow.

Integrated Valved Exhaust System

Electronically controlled valves switch between a refined OEM+ sound and a fully open, aggressive exhaust tone, controlled from the supplied wireless remote.

Full System From The Downpipes Back

Replaces the entire factory exhaust behind the downpipes in one kit - mid section, rear muffler and tips.

Stainless Steel Construction

Mandrel-bent stainless throughout for consistent bore, corrosion resistance and long service life.

Quad Tips In Your Choice Of Finish

Black, chrome or carbon fibre style tips, selected at checkout.

Direct Bolt-On Fitment

Designed specifically for the G80, G82 and G87 using factory mounting locations for straightforward installation.

Performance Benefits

When paired with supporting modifications and tuning, this exhaust system can provide:

• Increased exhaust flow and reduced backpressure
• Faster turbo spool and improved throttle response
• A deeper, fuller and more aggressive exhaust tone
• Near-standard volume with the valves closed
• Weight reduction over the factory exhaust

Performance gains may vary depending on supporting modifications and tuning.
