Which valved exhaust for a BMW M2 Competition F87?
The Rog system for the BMW M2 Competition F87 is a valved cat-back exhaust in 304 stainless steel or titanium, built to your VIN for the 410 hp, 550 Nm twin-turbo S55. You choose the six-cylinder's timbre (Standard, Equal Length or Equal Length + Z-pipe), and titanium takes significant weight off the rear compared with the 21.2 kg factory system.
Sound, options and fitting in detail: our BMW M2 Competition F87 guide.
In 2018, the M2 received the finest of gifts: the M3 F80’s S55 in place of the N55. The M2 Competition F87, built from 2018 to 2021, draws 410 hp and 550 Nm from it, with a forged crankshaft and a twin-turbo architecture heavily oversized for those figures. The preceding M2 N55 and the following M2 G87 each have their own page.
The S55 inherited a weak point: a subdued factory sound, with a 21.2 kg exhaust, resonators included, that does not tell the story of what is happening under the bonnet. Here, you choose the tone. In Standard, the twin-turbo expresses itself raw and voluminous; in Equal Length, two pipes of the same length synchronise the pulses and the note rises, smoother and less rasping; Equal Length + Z-pipe pushes towards the exotic top end of a naturally aspirated Japanese engine.
This valved cat-back, built to your VIN, is fixed without welding using clamps and gaskets in about two hours. With the valves closed, the Competition keeps a voice close to stock; open, it finally sounds like the little M3 it is. Your choice: the factory control or the Rog remote.
Sold under the “Manifold” option, the catalysed downpipe only gains power with an ECU remap, and otherwise remains a matter of sound and weight. Owners who drive on the road take the 200-cell variant, which keeps the S55’s emissions control; the 100-cell one is accepted or not depending on the car and the rules in your country, and the decat version is reserved for track use. In titanium, the exhaust weighs around 40% less than in 304 stainless steel and comes in brushed, gold or purple.

Questions about the BMW M2 Competition F87 3.0T exhaust.
Can an M2 CS F87 take the Competition’s exhaust?
The page is set up for the M2 Competition F87 from 2018 to 2021; for another F87 version, send us the VIN before ordering, and we check compatibility before manufacturing.
Why is the M2 Competition said to be an ideal base for Stage 2?
Because its S55 is detuned compared with the M3: the headroom is already in the engine, and with a downpipe and an ECU remap at an approved tuner, the published Stage 2 figures reach 530 hp and 720 Nm, without imposing anything on the cat-back alone.
BMW M2 Competition F87 3.0T with a Rog exhaust: what should you know about vehicle inspection?
With the cat-back only or the 200-cell sports catalytic converter, emissions control is retained: present the car with the valves closed. The 100-cell brings more sound and flow, and whether it is accepted at the emissions test depends on the car and local rules; the decat version is intended for track use.
Standard, Equal Length or Z-pipe on the Competition’s S55?
Standard for the raw grain of the twin-turbo and volume; Equal Length for a higher-pitched, smoother inline-six that transforms the M2’s identity; Equal Length + Z-pipe for the highest note, reserved for those who want to take the experience all the way.
How many kilos does an M2 Competition lose with titanium?
Our data puts the factory system at 21.2 kg, resonators included; our titanium cat-back weighs around 40% less than its stainless steel equivalent, though we do not quote an exact weight until it has been measured.
BMW M2 Competition F87 3.0T: Does a valved exhaust system drone?
No. With the valves closed, the gases flow through the whole rear silencer 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 motorway.
BMW M2 Competition F87 3.0T: 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.

Valved exhausts and Australian checks
For a pink slip, roadworthy or safety certificate, the inspector checks the exhaust for leaks and secure mounting: a Rog system bolts onto the original mounting points. The cat-back keeps your factory cat, sports cats follow your state's rules, catless is track only, and your state decides.
On the road
Around town, valves closed keep your car very close to stock, and you open them whenever you like, on an open road or at the track.
Your documents
Each system is built from the VIN on your rego papers, and we send its technical documentation free on request, for your registration authority or your insurer.
Your insurance
Many policies treat an exhaust change as a modification to declare, so let your insurer know: our free technical documentation makes it easy.
