BMW F80/F82/F87, M3/M4/M2 Stainless Steel Valved Equal Length Z Pipe Catback Exhaust

A complete stainless valved exhaust for the S55-powered BMW F80 M3, F82 M4 and F87 M2 Competition - 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.

The S55's two turbochargers feed the exhaust unevenly on a factory system, which is where much of its flat, raspy note comes from. The equal-length Z pipe gives both banks matched-length pipes and crosses them over before the muffler, balancing the pulses for a smoother, fuller and deeper tone.

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 that twist across each other before the muffler, 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 F80, F82 and F87 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 smoother, fuller and more aggressive S55 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.
