Carbon fiber parts, exhausts and intakes for BMW

On a BMW, choosing an exhaust, an intake or carbon fiber parts starts with the chassis code. BYC Performance imports catback exhausts and downpipes, cold air intakes, prepreg dry carbon fiber body parts and engine bay parts from leading manufacturers around the world for the M2, M3, M4, M5, M6 and M8 and for some 2, 3, 4 and 5 Series chassis. Open your series below and look for your chassis code in the product name.

Catback exhausts and downpipes

A catback is the whole exhaust system from the catalyst or downpipe back to the tips. Most catbacks are Valvetronic and come with their own electronic control box and wireless remote; you open and close the valves with that remote. There are stainless steel and lighter titanium versions; titanium comes in gold, blue, purple or original titanium color, and the tips can be matte carbon fiber, gloss carbon fiber, gloss black or stainless steel. On the M models, single, double and equal-length mid-pipe designs differ in sound character and flow.

Exhausts are engine-specific. The 3 Series G20 and 4 Series G22 have separate systems for the B48 and B58, and on the M2 F87 the N55 and S55 do not share an exhaust. The M2 G87, M3 G80 and M4 G82 use the same S58 catbacks and downpipes, and the M5 F10 and M6 F06, like the M5 F90 and M8 F92, share systems too. Downpipes come 200-cell catted or catless (de-cat). Before buying a de-cat downpipe, check the emission rules where the car will be driven. Ask on WhatsApp whether your car will need a software update after a downpipe or intake.

Cold air intakes

A cold air intake replaces the box and pipes the engine breathes through, with the aim of feeding it cooler air. There are versions for the S55 in the M3 F80 and M4 F82, the S58 in the M3 G80 and M4 G82, and for the M5 F10 and M5 F90. They come in carbon fiber, titanium and silicone; behind-grille versions draw air from right behind the front grille. You can pick a grey, red, blue, black or green air filter.

Carbon fiber body parts

Most body parts, from front lips to trunk lids, are prepreg dry carbon fiber, and some also come in forged carbon. You can order any carbon part in gloss or matte finish; you make the choice on the product page. Abbreviations such as CS, CSL, GTS, MP and V in the names describe the design; the products are not original BMW parts.

Engine bay and interior

For the M2 G87, M3 G80 and M4 G82 there are carbon fiber 3-point and 4-point strut braces and oil cooler guards in aluminum or carbon fiber. The M3 G80 and M4 G82 also get an aluminum strut brace, a carbon fiber engine cover and a titanium engine bolt kit. A 3-point brace ties the two strut towers to the front panel at one point, a 4-point brace at two. For the interior there are magnetic carbon fiber paddle shifters that fit F and G Series BMWs.

Frequently asked questions

How do I know a part fits my car?

The product name lists the chassis codes the part fits, for example 3 Series G20 / 4 Series G22. Some exhaust names also include the engine code. Parts for facelift chassis have "LCI" in the name. If your chassis code is not in the name, ask on WhatsApp before you order.

How do delivery and warranty work?

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