M4 F82 / F83

Carbon parts, exhausts and cold air intakes for the BMW M4 F82 and F83

For the S55 engine in the M4 F82 you can choose a Valvetronic catback exhaust, downpipes and a cold air intake, and for the body prepreg dry carbon fiber hoods, front lips, diffusers, side skirts and spoilers. The exhausts, intakes and body parts are imported from leading manufacturers around the world.

Catback exhausts and downpipes for the S55

On the S55, the catback takes over where the downpipes end and runs to the tips. The M4 F82 Valvetronic catbacks differ in mid-pipe layout, and the layout changes the character of the sound. The single mid-pipe system merges the lines into one pipe and sounds cleaner and more tonal, which suits daily driving. In the double mid-pipe system two pipes run separately and the sound is harder and fuller. In the equal-length mid-pipe system both lines are the same length, so the exhaust pulses travel the same distance and the sound is more even at high revs.

The titanium versions of the single and double mid-pipe systems are lighter than stainless steel and come with a 70, 76 or 90 mm pipe diameter in gold, blue, purple or original titanium color. For the tips you can pick stainless steel, gloss black, or carbon fiber in gloss or matte finish. The electronic control box and wireless remote supplied with each system open and close the valves.

The downpipe connects the turbochargers to the catback. The 200-cell catted downpipe has a catalytic converter. The heat-shielded and plain stainless steel downpipes give no catalytic converter details in their names, so ask on WhatsApp whether they are catted before ordering. Before fitting a de-cat downpipe, check the emission rules where the car is driven; send software questions on WhatsApp too.

Cold air intake systems

A cold air intake replaces the factory air filter and airbox. On behind-grille systems the filters sit right behind the front grille and take air straight from the front; this layout also comes in titanium. Other options include prepreg dry carbon fiber and titanium systems. Titanium adds a titanium color, and every system offers a grey, red, blue, black or green filter. All are for the S55 engine.

Carbon fiber body parts

The body parts are prepreg dry carbon fiber, and abbreviations such as MP, CS, PSM and GTS in their names refer to the design style. Hoods come in GTS vented, VRS vented and IMP designs. Front lips, flaps, a front bumper and fenders are available for the front, side skirts for the sides, and diffusers, a rear bumper and spoilers for the rear. The CSL trunk lid is for the M4 F82 only. For the mirror caps you choose between prepreg dry carbon fiber and marble-patterned forged carbon. For the cabin there are also magnetic carbon fiber paddle shifters.

Chassis and engine fitment

Parts named "M3 F80 / M4 F82" are sold for both models; other parts for the sister model are in the M3 F80 category. The trunk lid is chassis-specific, and for rear parts such as the rear bumper, diffusers and spoilers, confirm Sedan or Coupé fitment on WhatsApp before ordering. The F83 Convertible does not appear in any product name, so F83 owners should ask first, even for front parts. Exhaust names also list the M2C, which is the S55-engined M2 Competition; the standard M2 F87 with the N55 engine has a different exhaust, and these catbacks and downpipes do not fit it.

Frequently asked questions

Do I need to buy the catback and downpipe together?

No. They replace different sections of the exhaust and can be fitted separately.

Do these parts fit the M4 G82?

Parts without G82 in the name do not. The G82 and G83 are the next generation, with the S58 engine and different bumpers and panels. For those cars, see the M4 G82 / G83 category.

How are the exhausts and intakes shipped?

Lead time for sourced-to-order parts is confirmed on WhatsApp right after your order. Parts ship via partner couriers and carry a 24-month BYC warranty against manufacturing defects.
