All our exhausts for this generation, version by version, are brought together on one page: BMW 5 Series G30 / G31 Valved Exhaust.
The 5 Series G30 and its G31 Touring were designed to string together hundreds of kilometers in calm. In gasoline form, the 530i and the 540i rest on two very different turbo engines, and each gets its own Rog exhaust. Here is what sets your car apart before you choose.

G30 sedan, G31 Touring
BMW unveiled the seventh-generation 5 Series in October 2016, and the G30 sedan reached dealers in February 2017. The G31 Touring followed: shown at the Geneva Motor Show in March 2017, it went on sale in June, with a 530i and a 540i xDrive in its range from the start.
The facelift, on sale in July 2020, redesigned the front end and the rear bumper, which now carries trapezoidal tips, and extended the 48-volt mild hybrid system that the 540i benefits from. The G30 gave way in 2023. Driver's sedan or family wagon, the use differs from one body to the other; for the exhaust, the same engine gets the same exhaust in the G30 and in the G31.
530i or 540i: two engines, two product pages
The 530i entrusts the 5 Series to the B48, a 2.0-liter four-cylinder that produces 252 hp and 350 Nm, with that torque available from 1,450 rpm up to 4,800. These figures did not change with the facelift. The 540i gets the B58, a straight-six of 3.0 liters: 340 hp and 450 Nm until 2020, then 333 hp with the 48-volt starter-generator, which briefly adds 8 kW, or 11 hp, when pulling away again.
The two engines do not share the same exhaust: each has its own product page, valid for the sedan as for the Touring. Your VIN tells us the engine, the transmission and the model year; the product page covers cars from 2018 to 2023, and a 2017 G30 is checked the same way before manufacture.
The 520i, the 530e plug-in hybrid and the V8 M550i stay outside these two product pages. The M550i has its own guide; for the other two, send us the VIN: we will reply in writing on what we can make.

The B48, a four-cylinder for the long haul
The 530i's B48 is a direct-injection 2.0-liter, boosted by a twin-scroll turbo: the gases from the cylinders are split between two volutes, which helps the turbine respond at low revs. That is what gives a sedan of this size its peak torque at just over 1,400 rpm.
To the ear, a four-cylinder does not run like a six: its pulses are further apart, its grain firmer, rougher when the turbo builds boost. Under a factory 530i, this character is almost entirely erased. Once freed, it gives the 5 Series a frank bass note at start-up, then a voice that tightens with every surge up a highway slip road.
The B58, the 540i's six-cylinder
The B58 lines up six cylinders over 3.0 liters, with a twin-scroll turbo and direct injection. It is also found in the 340i F30, the 840i G14 to G16 or the M340i G20: an engine renowned for its flexibility, which pulls hard from mid-range and climbs smoothly to the red zone.
A straight-six is balanced by nature, and its pulses follow one another closely: the note is continuous, round at idle, increasingly metallic as the revs climb. It is the richest voice of the two product pages, and also the one the factory exhaust lets through the least, in the sedan as in the Touring.
What the G30 keeps to itself
A 5 Series is judged by its silence at cruising speed, and the factory exhaust contributes greatly to it. Its mufflers are bulky, designed for noise regulations and for the comfort of the rear seats, and the standard valves only open when the car decides. With a warm engine, at a steady pace, the 530i and the 540i let only a breath reach the cabin.
A valved exhaust solves this problem according to the moment. Closed, the gases pass through the muffler chambers, and the G30 returns to a level close to standard for an early start or a highway stage. Open, they take the short path: the B48 or the B58 makes itself heard from outside, at start-up as when pulling away.
The standard valves and your driving modes
The G30's factory rear muffler has valves, driven by an electric motor: the BMW parts catalog provides them for the 530i as for the 540i, in rear-wheel drive and xDrive, before and after the facelift. That is what makes the Factory option on both product pages possible: the Rog exhaust provides their mounting points, your garage moves the valves from the factory exhaust onto it, and the 5 Series mode selector keeps controlling them.
The Rog option, for its part, supplies valves already fitted to the exhaust and a two-button control unit. You choose open or closed, and the position holds, whether the car is in Comfort or in Sport. On a Touring setting off loaded for the holidays, it is a simple way of staying in control: closed for the highway, open for a mountain road.
Straight pipe or resonator under a 5 Series
On both product pages, the character of the sound is chosen at the same price. The straight pipe lets all the engine's grain through, which suits the 530i's four-cylinder if you like its rasp. The resonator gives a rounder and slightly softer voice, a setting that suits a touring 540i, without taking away the exhaust's sporty character.
Tips and shades
On the finish side, the 530i and the 540i are entitled to the same tips: the Rog tips, included, come in chrome, gloss black and blued titanium; as an option, the tips with the M logo come in forged carbon, black carbon or carbon blended with titanium. A G30 can also receive its exhaust without tips, to keep a sober rear bumper.
Titanium makes the exhaust about 40% lighter than 304 stainless steel, for an identical design; its three shades, brushed, gold and purple, are offered at the same price. Under a 540i, stainless steel keeps the six-cylinder's roundness; titanium brightens its note in the revs.
What the two product pages cover
Each product page covers the cat-back, from the downpipe outlet to the tips, and offers the downpipe itself as an option under the name "Manifold": you can do without it, or take it as a sport catalytic converter, with 200 or 100 cells, or in a catalyst-free version, intended for the track. Only the 200-cell keeps emissions control.
With the cat-back alone, the 530i and the 540i keep their control unit and their power: the exhaust changes the voice, not the figures. For extra horsepower, the downpipe has to be combined with a remap carried out by a tuner. Your exhaust is made by Rog from the G30's VIN, then fitted by your garage, with no welding or cutting.
Configure your exhaust.
How the exhaust is put together
On the 530i as on the 540i G30, the Rog cat-back starts at the downpipe outlet and runs to the tips, passing through the mufflers and their valves. The downpipe, placed just after the turbo, carries the catalytic converter: it is an option on each product page, on the "Manifold" line.
Each choice explained in detail, from sound to material: How to configure your exhaust.
Your exhaust for 530i and 540i G30
The 530i and 540i product pages are set up in the same way: a material, 304 stainless steel or titanium in three shades, then a character, straight pipe or resonator at no extra cost. Next come the optional downpipe, the choice between the 5 Series valves and our remote, and finally Rog tips or carbon tips stamped with the M logo.
The price of each configuration is shown on the product page, in your currency.

Questions.
Do my 530i and my 540i G30 get the same exhaust?
No. The B48 four-cylinder and the B58 six-cylinder each have their own product page and their own exhaust. For the same engine, however, the G30 sedan and the G31 Touring share the same Rog exhaust, and your VIN confirms everything before manufacture.
Is the facelifted 540i, at 333 hp and mild hybrid, covered?
Yes. The 540i product page covers both versions of the B58, at 340 hp before the facelift and 333 hp after, in the sedan as in the Touring. Your VIN is checked before manufacture starts.
And for a 520i or a 530e G30?
These two versions are not on either product page. Send us your 5 Series' VIN: we will tell you in writing what we can make for it.
Will my 5 Series' mode selector still control the valves?
With the Factory option, yes: the exhaust takes the mounting points of the standard 530i or 540i valves, your garage refits them there, and Comfort or Sport keep controlling them. With the Rog option, it is your thumb on the remote that decides, Sport mode or not.
Which voice for a 530i, which voice for a 540i?
The 530i's B48 takes on a firm, rasping grain, more marked when the turbo builds boost; the 540i's B58 sings continuously and turns metallic in the revs. Measured on our sound scale, the factory G30 rates 3 out of 10; with the Rog cat-back alone, valves open, it rises to 7.
Do I need to say whether my G30 is an xDrive?
Your VIN is enough: it gives us the transmission, which we check before manufacture, particularly if you add the optional downpipe. The configuration chosen for your car is confirmed to you in writing.
A question about your 530i or 540i?
Put it to the Rog Advisor or write to us: we reply in writing, within 24 hours.
