Which valved exhaust for a BMW 640i F06, F12 or F13?
The Rog system for the BMW 640i N55 is a valved cat-back exhaust for the F06 Gran Coupé, F12 convertible and F13 coupé, built to your VIN in 304 stainless steel or titanium for the 320 hp, 450 Nm turbo six-cylinder. Valves open, the 6 Series gains an assertive presence from idle; closed, it remains a hushed grand tourer.
Sound, options and fitting in detail: our BMW 640i F06 / F12 / F13 guide.
The 640i comes as the four-door Gran Coupé F06, the Convertible F12 and the Coupé F13, three 6 Series silhouettes built around the N55, a 3.0-litre single-turbo straight six, smooth and robust, delivering 320 hp and 450 Nm. Today it is a GT whose value for money is hard to beat. All three body styles take the same system, documented for cars from 2012 to 2017; outside that period your VIN settles it, and the M6 has its own page.
Tuned for hushed cruising, the factory system says nothing about this engine's deep, mechanical tone. With the Rog cat-back and its valves open, the 6 Series gains an assertive presence from idle, a raspy, full-bodied climb and crisp crackles on the overrun; with the valves closed, it returns to the discretion of a grand tourer. That is the dual personality a GT should always have.
Under the body nothing is welded: the system, bent to your VIN, connects with clamps and gaskets in around two hours, and the factory valve control stays active, or the Rog remote replaces it.
The “Manifold” option sells the N55 downpipe, with its catalytic converter; without a remap it only changes the voice and saves a little weight. A 640i covering European highways keeps its emissions control with the 200-cell variant; the 100-cell is accepted or not depending on the vehicle and the rules of your country, and the decat version is reserved for track use. Among 6 Series owners, 304 stainless steel and titanium, about 40% lighter and tinted, share the honours.

Questions about the BMW 640i N55 F06 / F12 / F13 3.0T exhaust.
Does the 640i Coupé F13 or Convertible F12 take the same system as the Gran Coupé F06?
Yes: all three 640i body styles share this system, with the same N55 and the same material and downpipe options. We check the VIN of your Coupé or Convertible before manufacture, as for every order.
Does the N55 in a 640i handle a Stage 2 well?
The Stage 2 figures published on this listing are 390 hp and 590 Nm, with a downpipe and a remap at an approved centre; the cat-back alone runs on the factory engine management.
BMW 640i N55 F06 / F12 / F13 3.0T with a Rog exhaust: what should you know about vehicle inspection?
In its most common configuration, cat-back alone or a 200-cell downpipe, the GT keeps its catalytic converter, and with its valves closed it is as discreet as in the showroom: that is how it should be presented. A 100-cell downpipe will be accepted or not depending on the vehicle and the rules of your country, while the decat version remains reserved for track use.
Does a GT like the 640i need a sports exhaust?
It gains a second personality: valves closed, cruising comfort stays intact; valves open, the straight six finally makes itself heard on the weekend drive, roof down for the F12 Convertible.
Will a 640i F06, F12 or F13 drone on the highway?
No: with the valves closed, the gases run through the cruising muffler and the cabin keeps the calm of a grand tourer, even after several hours on the road.
BMW 640i N55 F06 / F12 / F13 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.
