The BMW M2 G87 exhaust in detail.
The M2 G87 is the last compact rear-wheel-drive BMW M offered with a manual transmission. Under its hood sits the M3’s S58, detuned to 460 hp and 550 Nm, with its forged crankshaft and two turbos. This page covers M2 G87s built since 2023; the M2 Competition F87 and M3 G80 have their own pages, and your VIN is used to confirm the system before manufacturing.
Every review pointed it out: to the ear, the G87 disappoints. Its 22.3 kg factory exhaust, designed for Euro 6d standards with a particulate filter and a massive muffler, makes it quieter at start-up than a diesel hatchback. This valved cat-back gives it real presence, and you choose the tone: Standard for the raw twin-turbo, Equal Length for a higher-pitched, smoother note, Equal Length + Z-pipe for a very high, exotic register.
With the valves closed, the M2 stays close to its factory sound; open, it expresses itself fully. Weld-free fitting, with clamps and gaskets, in about two hours; controlled by the factory control or by the Rog remote, whose box sits in the trunk.
The “Manifold” option on the page sells the S58’s downpipe, which carries the catalytic converter; without a suitable map, it only adds voice and a little lightness. On an M2 driven on the open road, the 200-cell keeps the exhaust gas treatment required by Euro 6d; the 100-cell is accepted or not depending on the car and the rules in your country, and the decat version is reserved for track use. It remains to decide between full, round 304 stainless steel and titanium around 40% lighter, in brushed, gold or purple, which lightens the rear of an already very sharp compact.

Questions about the BMW M2 G87 exhaust.
Can a newer 480 hp M2 G87 take this exhaust?
The page covers M2 G87s built since 2023; for the 480 hp version, send the VIN before ordering, and we check compatibility before manufacturing.
Why does the M2 G87 gain so much at Stage 2?
Because its S58 is deliberately detuned compared with the M3: with a downpipe and an ECU remap at an approved tuner, the figures published for the G87 reach 700 hp and 900 Nm, whereas the cat-back alone requires no change to the ECU.
BMW M2 G87 with a Rog exhaust: what should you know about vehicle inspection?
It arrives discreetly, valves closed and voice close to stock, with a catalytic converter retained behind the cat-back alone or the 200-cell downpipe; the 100-cell is accepted or not depending on the car and the rules in your country, and the decat version is reserved for track use, well away from testing centres.
Which design gives the M2 G87 the best sound?
Standard if you like the rough grain of the twin-turbo; Equal Length for a higher, smoother note that changes the car’s identity; Equal Length + Z-pipe for the highest-pitched and most exotic register.
Does titanium noticeably lighten the rear of the G87?
Yes: against a factory system listed at 22.3 kg on the page, our titanium cat-back weighs around 40% less than the same design in stainless steel, a welcome saving over the rear axle of such a lively rear-wheel-drive car.
BMW M2 G87: Does a valved exhaust system drone?
No. With the valves closed, the gases flow through the whole rear muffler and the cabin stays calm at a steady speed. Our Rog exhausts are designed to avoid drone. Learn more: Why our systems stay calm on the highway.
BMW M2 G87: straight pipe or resonator?
On this model, two characters at the same price: the straight pipe for the raw sound of your engine, unfiltered, or the resonator for a rounder and slightly softer voice. Either way, the exhaust stays fully sporty. Learn more: Exhaust resonator: what does it do? Straight pipe or resonator, which sound to choose.
