BMW S58 Downpipe & Exhaust Upgrade Guide – G87 M2, G80 M3 & G82 M4
The BMW S58 platform in the G87 M2, G80 M3 and G82/G83 M4 has a large aftermarket, but the most useful upgrade path depends on whether you are changing exhaust flow, sound, underbody protection or driver control. Racing Lab currently carries several products that sit in different parts of that package.

These are current Racing Lab products directly related to the topic below.
200-cell catted downpipes
For owners looking at a high-flow catted setup, Racing Lab lists the BMW S58 3.5-Inch 200-Cell Catted Downpipes with Heat Shield.
A catted downpipe is generally chosen by drivers who want a freer-flowing exhaust path while retaining a catalytic converter. Fitment, tuning requirements, noise and local road-use rules should all be checked before ordering or installing.
Catless S58 downpipes
Racing Lab also offers BMW G8X S58 One-Piece Catless Downpipes for G87 M2, G80 M3 and G82/G83 M4 applications.
Catless exhaust components are intended for specific performance or motorsport use cases and can have legal, emissions and noise implications. Confirm the requirements that apply to your vehicle and location before installation.
Mid-pipe and Z-pipe options
Downpipes are only one part of the exhaust system. Racing Lab also carries the G80/G82/G83 GT4 Z-Pipe and the G87 M2 GT4 Z-Pipe, along with other G87 exhaust options.
Exhaust valve control
For G8X owners who want more control over the factory exhaust valve behaviour, Racing Lab lists an Exhaust Valve Controller Module for BMW G8X M3/M4.
Protect the oil cooler on low cars
Exhaust parts get most of the attention, but track and lowered cars also benefit from thinking about protection. The Oil Cooler Skid Plate / Undertray for BMW G8X M2/M3/M4 is a different kind of upgrade: it is aimed at protecting a vulnerable underside area rather than changing engine output.
Build around how the car is used
A road car, a tuned weekend car and a track car do not need the same combination of parts. Start by deciding whether your priority is sound, flow, protection or track durability, then choose the relevant component rather than replacing everything at once.
