What each part does on the M177 engine

The downpipe is the first section of exhaust after the turbo. Every exhaust gas leaving the engine goes through it, so it is a key part of the system. The M177 is a twin-turbo engine, so it has two turbos and the downpipes serve both. The listing covers 2015 to 2021 cars.

The exhaust is the rear section. It carries the gas to the tips and sets how the car sounds. Valved exhausts are quieter when the valves are closed. The C63 exhaust is the larger and higher priced part. Read the product page for the valve, tip and finish details.

Gas leaves the engine, spins the turbos, then flows through the downpipes, the midpipe and the exhaust to the tips. Each section is a separate part, which is why you can buy them in steps. Every part is made to order, so it is built after you place your order.

How to choose: one part or the full system

The downpipes are the simple first step and cost far less than the exhaust. The exhaust changes the rear of the car, so it is a larger decision.

If you want both, they are separate products and can be bought together or one after the other. Delivery is free worldwide. There is no midpipe listed for this car right now.

What to check before you order

Write down your chassis code, model year and engine before you start. Keep your registration card close, so you can compare it with the Fits list. If the list does not match your car, do not order that part. If you are unsure, ask us on WhatsApp first.

  1. Exact chassis and years. Open the product page and read the Fits list. Match your chassis code and model years to it before you buy. The downpipe title shows 2015 to 2021, so confirm that your car sits inside that range.
  2. Tune. A tune may be needed after a downpipe, and some cars show a check-engine light without one.
  3. Road or track. Some parts are for road use and some are for off-road and track use only. Check the rules where you drive.
