Best valved exhaust for BMW 650i F12 / F13 N63

Your vehicle.

All our exhausts for this generation, version by version, are brought together on one page: BMW 6 Series F06 / F12 / F13 Valved Exhaust.

In the third generation of the 6 Series, the 650i is the V8 version: above the six-cylinder 640i, below the M6. It comes as the F12 convertible and the F13 coupe, two large four-seaters designed to travel fast and far. Before choosing its line, here are the traits of the car that matter for the exhaust.

Convertible first, coupe afterwards

BMW opened the F1x generation of the 6 Series with the convertible. Presented at the Los Angeles show in November 2010, the 650i Convertible F12 reached markets in spring 2011, topped with a fabric roof. The F13 coupe followed during the same year. The four-door Gran Coupe F06 came only in 2012 and is not covered by this product page.

Our product page targets 650i cars of model years 2011 and 2012, as convertible and as coupe. Both body styles take the same Rog line. Your VIN lets us confirm the car, its body style and its engine version before launching the build.

These two silhouettes appeal to the same driver: someone who likes to swallow miles in comfort, but expects a V8 to make itself heard when the road allows. That is the whole point of the exhaust on this car.

407 hp, then a revised V8

In its first version, the 650i's N63 develops 407 hp, or 300 kW, between 5,500 and 6,400 rpm, and 600 Nm between 1,750 and 4,500 rpm. The coupe, which weighs around 1,770 kg, reaches 100 km/h in 4.9 seconds. With such torque from 1,750 rpm, the 650i pulls away effortlessly in any gear.

BMW later fitted the 650i with a revised version of the V8, quoted at 450 hp and 650 Nm. This product page is drawn up for the 407 hp version: if your 650i quotes 450 hp, send us its VIN before ordering, and we will reply in writing.

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

Eight-speed gearbox and xDrive

The 650i F12 and F13 has an eight-speed automatic gearbox. It exists in rear-wheel drive and, depending on the market, in xDrive all-wheel drive. These differences have no effect on the rear exhaust: the Rog line is the same for a 650i xDrive and a rear-wheel-drive car.

What matters for the line is the body style and the engine version. The convertible and the coupe share the same line, and the 407 hp version is the one the product page covers.

The N63, a V8 with an inverted architecture

The N63 displaces 4,395 cm³ spread over eight cylinders in a V. Its particularity lies in its layout: the exhaust manifolds and the two turbos sit in the centre of the V, between the two banks of cylinders, and the intakes run outside. It is the opposite of the classic V8 layout. BMW was the first to fit this scheme to a production engine, in 2008, with the X6 xDrive50i.

This layout shortens the path of the gases between the cylinders and the turbos, which favours a quick response. It also explains the shape of the front section: each turbo opens onto its own downpipe, with its catalytic converter, and these two downpipes leave the top of the engine for the floor.

This same V8 equipped the 550i F10 and the X5 50i; the 640i has a six-cylinder and the M6 a more powerful V8, each with its own guide. The 650i's line fits only the 650i.

The V8's voice, and what holds it back

A V8 has a sound that sixes cannot imitate: a deep rumble at idle, more widely spaced pulses, then a roll that thickens with every rise in revs. On the 650i, this character is almost inaudible as standard.

The two turbines absorb part of the energy of the gases before they reach the line. Then the factory mufflers, sized for a grand tourer, pass them through large chambers. The result is pleasant when cruising, but it leaves the V8 at the level of a rumour, even with the roof down. In the well-insulated F13 coupe, you can barely tell an eight-cylinder is working under the long bonnet; in the F12 convertible, with the roof folded, you mostly hear the wind. For a car chosen partly for its engine, the gap is striking.

With the Rog line, flaps open, the N63 rumbles from start-up, rolls hard on pull-away and asserts itself under acceleration. The straight pipe keeps this raw grain; the resonator gives the V8 a rounder, slightly softer voice, welcome on a convertible, where you hear the exhaust from very close. Both cost the same price.

Factory flaps and Rog flaps

As standard, the rear mufflers of the 650i F12 and F13 include flaps, which the car opens and closes itself according to driving conditions. The Rog product page lets you decide who controls them.

With the Factory option, our line is delivered with the place for the 650i's flaps: your garage transfers those of the factory line, and the car keeps managing them as before. With the Rog option, the line arrives equipped with our flaps, a two-button remote and a box hidden in the boot: one press opens them, another closes them, and they hold that position however you drive.

On the convertible, the remote has a particular charm: with the roof folded, you set the V8's volume to suit the scenery, discreet in a village, open on a mountain road.

Tips and material

The outlets receive your choice of Rog tips, included, in chrome, gloss black or blued titanium, or carbon tips with the M logo, as an option, forged, black or combined with titanium. An order without tips remains possible.

With 304 stainless steel, the N63 keeps a dense bass, and the line gets through winters without a murmur. Titanium, which weighs roughly 40% less than stainless steel for an identical design, relieves the rear of a heavy car and makes the note clearer at the top of the rev counter; it comes tinted brushed, gold or purple, for the same price.

What the 650i product page covers

The 650i product page pairs the cat-back with, as an option, the two N63 downpipes under the name "Manifold": factory, 200-cell, which keeps the emissions control in service, 100-cell, or catalyst-free, a version meant for the circuit.

With the line alone, the 650i keeps its mapping and its 407 hp: it gains a voice and a little less weight. Extra power requires the downpipes and a remap at a tuner. The line is made from your 650i's VIN; your garage then fits it without welding or cutting.

How the exhaust is put together

On the 650i, the Rog cat-back gathers the gases from the two downpipes and carries them to the rear of the 6 Series: pipes, mufflers, flaps. The two N63 downpipes, one behind each turbo with its catalytic converter, make up the front section, which the product page lists under the "Manifold" option.

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

Three recommended configurations.

• Grand tourer

  • Stainless steel
  • Factory downpipes
  • Resonator
  • Factory valves

  For an F13 coupe that strings together long stages: the V8 takes on a rounder, slightly softer voice, the front section stays BMW's, and the car keeps managing its flaps.

• Roof down

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

  For an F12 convertible that comes out on fine days: the 200-cell downpipes thicken the V8, the emissions control stays active, and the remote sets the volume as the scenery changes.

• Tuned V8

  • Stainless steel
  • 100-cell sports catalytic converter
  • Straight pipe
  • Carbon tips with the M logo

  For a 650i headed for a remap: the 100-cell downpipes free the N63's two turbos, stainless steel keeps the V8's thick bass, and carbon signs the rear.
