BMW F80/F82/F87, M3/M4/M2 Stage 2+ Performance Package

Everything an F8X needs for Stage 2, in one order. This Stage 2+ Performance Package combines our performance air intake, catless downpipes with heat shielding, valved stainless steel catback exhaust and turbo inlet pipe kit for the BMW F80 M3, F82 M4 and F87 M2 Competition - four upgrades designed to work together on the twin-turbocharged S55.

Each part removes a restriction the next one depends on. The intake and turbo inlet pipes let the turbochargers draw more air, the catless downpipes remove the biggest restriction on the exhaust side, and the valved catback carries that flow out while giving you control of the volume. Together they give a Stage 2 tune the hardware it needs to make its power - and bought as a package they cost less than buying each part separately.

What's Included

Performance Air Intake

Twin high-flow filters in enclosed heat shields with an oversized intake pipe, replacing the restrictive factory airbox for more airflow and a sharper induction note.

Catless Downpipes with Heat Shield

A matched pair of mandrel-bent stainless downpipes with full woven heat shielding - the largest single reduction in backpressure available to the S55.

Stainless Steel Valved Catback Exhaust

A full valved catback with quad tips, switching between a refined OEM+ tone and a fully open, aggressive note. The M3 and M4 receive the F80/F82 system; the M2 Competition receives the matching F87 system - select your car at checkout.

Turbo Inlet Pipe Kit

Larger-diameter inlet pipes that replace the restrictive factory items, letting both turbochargers breathe more freely and spool more readily.

What Gains Can You Expect?

The S55 responds strongly to tuning, and this is the hardware a Stage 2 tune is built around. With these parts installed and a quality Stage 2 ECU tune, these are the figures owners and tuners commonly report:

Factory: M3 / M4 317kW / 550Nm (331kW Competition), M2 Competition 302kW / 550Nm
Stage 2 on 98 RON pump fuel: approximately 410-430kW (550-580hp) and 700-750Nm at the crank
Stage 2 on an ethanol blend: 450kW+ (600hp+) is regularly achieved

That is roughly 80-110kW and 150-200Nm over a factory car, with the M2 Competition reaching similar figures from its slightly lower starting point.

Results vary with the tuner, fuel quality, ambient conditions and the health of the car. These figures are a guide, not a guarantee.

Gearbox And Drivetrain

The 7-speed M DCT handles Stage 2 torque well, and a transmission tune is recommended to sharpen shift speed, launch control and gear hold to match the extra power. On 6-speed manual cars, the factory clutch may begin to slip at Stage 2 torque levels, so an upgraded clutch is worth planning for.

Performance Benefits

Approximately 80-110kW more at the crank on 98 RON with a Stage 2 tune
150-200Nm more torque, arriving earlier in the rev range
Faster turbo spool and sharper throttle response
An adjustable exhaust note, from quiet cruising to full race sound
A complete, matched hardware base instead of piecing parts together

Vehicle Fitment

Please Note

This is a hardware package - tuning is not included. An ECU tune is required to run catless downpipes and to realise the gains above. Please organise a reputable tuner experienced with the S55. A crank hub upgrade is also widely recommended on tuned S55 engines.

Removing a catalytic converter is not legal for road use in Australia. This package is intended for off-road, track and motorsport use only, and it is the owner's responsibility to comply with the regulations in their state.

Professional installation is recommended.
