Best valved exhaust for BMW M2 G87

Your vehicle.

All our exhausts for this generation, version by version, are brought together on one page: BMW M2 G87 exhaust system.

The second-generation M2, the G87 exists only as a coupé, and its mechanics come straight from the current M3 and M4. For the exhaust, the equation is simple: a top-class engine, a factory exhaust designed to be forgotten, and therefore a considerable sound margin. Here is the essential to know about your car.

A second-generation M2

BMW unveiled the M2 G87 in October 2022, for a global launch in April 2023. It is assembled in Mexico, at BMW's San Luis Potosí plant, alongside the 2 Series Coupé whose silhouette it takes on.

Where the M2 F87 had known two engines, the N55 then the Competition's S55, the G87 received from the outset that of the M3 and M4 of its generation. It keeps the little M's recipe: a two-door coupé, a single drive layout, rear-wheel drive, and a short wheelbase.

In 2024, BMW gave it more power and black exhaust tip trims as standard. The Rog product page covers the G87 since 2023; for a car built after this update, your VIN lets us confirm the exhaust before making it.

From 460 to 480 hp

At launch, the M2's S58 delivers 338 kW, or 460 hp, and 550 Nm between 2,650 and 5,870 rpm. It is allowed to rev up to 7,200 rpm, which leaves a boosted engine a fine reach.

Since the August 2024 production, power rises to 480 hp (353 kW), whatever the gearbox. Torque, on the other hand, depends on the transmission: 600 Nm with the M Steptronic, an unchanged 550 Nm with the manual gearbox.

Whether your G87 is from the first or the second version, your VIN tells us, and it is on that basis that we check compatibility, in writing, before launching manufacture. The same goes for an M2 CS.

Stage 2: published figures with the front section and an ECU remap carried out by a tuner.

Steptronic or manual, always rear-wheel drive

As standard, the M2 G87 gets the eight-speed M Steptronic gearbox, with the Drivelogic function and its three shift programmes. The six-speed manual is still offered as an option.

All the power goes to the rear. The active M differential can lock up to 100%, two complete settings of the car can be memorised on the steering wheel's M buttons, and the M Mode button on the console modulates the intervention of the driving aids.

For the exhaust, the gearbox does not matter: Steptronic or manual, the G87 gets the same Rog cat-back.

The S58 under an M2 bonnet

The S58 is the 3.0-litre straight-six of the M3 and M4 G8x, boosted by two turbos. In the M2, it keeps its forged crankshaft and an oil circuit designed for the heavy demands of the track, but BMW tunes it below its bigger sisters.

This tune leaves headroom, and the product page's bars, above, say what it accepts with the front section and a remap. The cat-back alone does not touch the control unit: your M2 keeps exactly its factory power.

The S58's voice in the G87

In the G87, the S58 speaks like a straight-six: a continuous voice, without jolts, deep at idle and increasingly taut as it approaches 7,200 rpm. Its two turbos dampen a share of the pulses, so that its voice is already filtered once before it even reaches the exhaust.

That is why the design of the exhaust weighs so heavily on this coupé: it decides what remains of this character once the gases reach the outlets.

Three designs for the G87

The Standard keeps the twin-turbo's rough grain and gives it the most volume: it is the deepest voice of the three, the one heard mostly at mid-revs.

The Equal Length equalises the length of the pipes before they join. The S58's pulses arrive in cadence, and the M2 changes identity: the note rises, becomes purer and more regular, with less rasp.

With the Z-pipe, the flows cross in a Z-shaped geometry, and the register climbs to the highest in our range for this engine, with the exotic accent of an engine that lives in the revs.

The character is chosen last, at the same price: the straight pipe delivers the S58 unfiltered, the resonator gives it a rounder and slightly softer voice.

Why the factory G87 stays so well-behaved

Our product page quotes 22.3 kg for the G87's factory exhaust. It was designed for the Euro 6d standard, with bulky silencers, and it is mainly the opening of its valves that gives it a voice.

BMW describes a rich sound, produced by an M-specific exhaust with electric valves. That richness nevertheless depends on the setting of the moment: valves closed, the gases pass through all the chambers, and the six-cylinder becomes discreet, to the point of surprising for an M of this calibre.

The Rog exhaust retains this two-state operation, with a much bigger gap between the two. Closed, it stays close to the factory level, which suits the neighbourhood in the morning; open, it gives the coupé a presence at last worthy of its engine.

Electric valves: your settings or our remote

The G87 has electric valves as standard, and the Rog product page lets you choose who controls them. Opt for Factory: the exhaust is prepared for them, your garage removes them from the standard exhaust to fix them on ours, and the G87 keeps opening or closing them in its own way.

With the Rog option, our valves arrive already in place, with a two-button remote and a small control unit hidden in the boot. The car's settings no longer change anything: open for leaving on a clear road, closed for coming home late.

Two pairs of outlets, well set back

At the rear, the G87 carries two pairs of outlets, placed far from the bumper's edges, a signature of this generation. The Rog exhaust keeps this layout, and you choose the finish: Rog tips included, in chrome, gloss black or blued titanium; carbon tips with the M logo as an option, in forged carbon, black or blended with titanium; or no tips at all.

The material follows the same principle of choice. 304 stainless steel offers a full bass and fears neither salt nor winter; titanium takes about 40% off the weight of the same stainless steel exhaust, less weight where a rear-wheel-drive car feels it most, on the rear axle, and is chosen brushed, gold or purple with no price difference.

What the product page covers on the M2

The cat-back starts at the outlet of the S58's two downpipes, one per turbo, which carry the catalytic converter. These downpipes are the exhaust's front section: the product page makes them an option, called "Manifold", with a 200-cell or 100-cell sport catalytic converter, or catalyst-free for track use.

Without them and without a remap, the G87 keeps its factory figures. The exhaust is made to your VIN, then your garage fits it with clamps and gaskets, without an angle grinder or a welding set.

How the exhaust is put together

On the M2 G87, the Rog cat-back takes over from the S58's two downpipes and runs to the two pairs of outlets, pipes, silencers and valves combined. Upstream, these two catalytic downpipes form the front section; the product page adds them on request, "Manifold" option.

Each choice explained in detail, from sound to material: How to configure your exhaust.

Three recommended configurations.

• Weekday and weekend

  • Standard
  • Stainless steel
  • No manifold
  • Resonator
  • Factory valves

  For an M2 used every day: the twin-turbo's grain rounded by the resonator, the standard front section kept, and the car's settings keeping control of the valves.

• The singing S58

  • Equal Length
  • Gold titanium
  • 200-cell sports catalytic converter
  • Straight pipe
  • Rog remote

  To hear the G87's six-cylinder climb towards 7,200 rpm with a clean, even voice, with a freer front section that keeps emissions control.

• Track

  • Equal Length + Z-pipe
  • Brushed titanium
  • Decat
  • Rog remote

  For a G87 that strings together track sessions: the highest register of the range, no restriction at the front, and valves that no longer close all day.
