The BMW 650i N63 F12 / F13 exhaust in detail.
F13 coupé or F12 convertible, the 2011 and 2012 model year 650i relies on the effortless power of a twin-turbo V8: the N63, whose two turbos sit in the vee, a layout BMW was among the first to adopt in series production. It delivers 407 hp and 600 Nm, with torque very present from low revs, ideal for a grand tourer. The 640i’s six-cylinder and the M6’s S63 correspond to other pages.
A cross-plane crankshaft V8 has a voice recognizable among all others, an irregular rumble at idle that rolls and hardens under acceleration. The 650i’s factory exhaust reduces it to a distant murmur, out of keeping with its strength. With the valves open, our cat-back gives the N63 back a marked rumble at start-up and a much more present one when accelerating, with the hushed whoosh of the turbos in the background. In the convertible, roof folded, the contrast with the closed position is even more enjoyable.
Installation touches nothing but the exhaust: clamps, gaskets, no welding and about two hours, for a system bent to your VIN and controlled by the original switchgear or by the Rog remote.
The “Manifold” option sells the downpipe that follows the N63’s turbos, where the catalytic converter sits; with factory engine management, it is limited to voice and weight. Coupé or convertible, the 650i keeps its exhaust gas treatment with the 200-cell downpipes; the 100-cell ones are accepted or not depending on the car and the rules in your country, and the decat version is reserved for track use. For the cat-back, 304 stainless steel that thickens the V8, or titanium that removes around 40% of the mass.

Questions about the BMW 650i N63 F12 / F13 exhaust.
Is the facelifted 650i, after 2012, covered?
Our page stops at the 2011 and 2012 650i; for a younger car, the VIN will let us compare the parts and reply before manufacturing.
With a downpipe and a new map, what does the V8 in a 650i deliver?
Strongly, like most twin-turbo V8s: the published Stage 2 figures are 494 hp and 746 Nm, with downpipe and a map by an approved tuner, on a well-maintained engine; the cat-back on its own does not touch the ECU.
Vehicle inspection for a 650i F12 or F13: which configuration?
That of a well-behaved grand tourer: valves closed, V8 brought back to its factory murmur, and catalytic converter retained with the factory or 200-cell front section; 100-cell versions are accepted or not depending on the vehicle and your country’s rules, and the decat version is reserved for track use.
In the F12 convertible, do you need to open the valves to enjoy the V8?
With the roof folded, the V8 is already easier to hear; with the valves open, the rumble becomes forthright, and with the valves closed the 650i remains a relaxing grand tourer.
Is titanium the better choice for the voice of a 650i’s V8?
304 stainless steel thickens the V8’s bass and stands the test of time; titanium lightens the system by around 40% for the same design and adds a touch of colour to the rear of the 6 Series.
BMW 650i N63 F12 / F13: 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 650i N63 F12 / F13: 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.
