Downpipes for better performance and freer exhaust flow
A downpipe is one of the most popular modifications for turbocharged cars and an important part of the exhaust system. By improving exhaust gas flow it reduces back pressure, helps the turbo spool faster and is a solid base for Stage 1 and Stage 2 tuning.
Browse downpipes by make:
BMW • Audi • Volkswagen • Mercedes • Honda • Toyota • Nissan • Subaru • Porsche
At Select Parts you will find a wide choice of downpipes for BMW, Audi, Volkswagen, Mercedes-Benz, Skoda, Seat, Cupra, Honda, Toyota, Nissan, Subaru, Porsche and many other makes. Our catalogue is built around RM Motors, which offers high-quality exhaust components with excellent fitment, made of stainless steel. We also carry carefully selected TurboWorks models with a very good balance of quality and price.
All downpipes are made of high-quality stainless steel and are designed for turbocharged cars. They suit daily use as well as more serious tuning projects where better turbo response and more efficient exhaust gas flow are the goal.
For the best result we recommend combining a downpipe with an exhaust heat wrap, a quality cat-back system or other parts from our exhaust range.
Advantages of a downpipe
- Faster turbo response.
- Better exhaust gas flow.
- Reduced back pressure.
- Suitable for Stage 1 and Stage 2 projects.
- Made of high-quality stainless steel.
- A wide choice of RM Motors and TurboWorks models.
If you are not sure which downpipe fits your car, the Select Parts team will help you choose by model, engine and the configuration you want.
What is a downpipe and what does it do?
The downpipe is the part of the exhaust system that connects the turbocharger to the rest of the exhaust. In tuning applications, a larger diameter and optimised flow reduce exhaust gas resistance and help the turbo respond faster. A downpipe is often part of a Stage 1 or Stage 2 setup.
What are the benefits of a sport downpipe?
The main benefits are freer exhaust gas flow, faster turbo response and the potential to optimise power and torque with suitable software tuning. Depending on the car and setup, the exhaust sound may change too.
How do I choose the right downpipe for my car?
A downpipe should be chosen by make, model, generation, engine, power output and the exact configuration of the exhaust system. For example, two BMW E90s can use different downpipes depending on the engine. If in doubt, contact Select Parts with your car details or VIN and we will check fitment.
How can I check if a downpipe fits my car?
Do not rely on the car model alone. Check generation, year, engine, power and, if needed, the OEM number or VIN. At Select Parts, fitment is listed on each product, and if you are unsure we can verify it before you order.
Is a remap needed after fitting a downpipe?
It depends on the car and the type of downpipe. Changes affecting the catalytic converter, DPF/GPF or ECU-monitored components may cause fault codes or require a software change. We recommend consulting a specialist for your specific car before fitting.
Which downpipe diameter should I choose – 63.5 mm or 76 mm?
The right diameter depends on the engine, turbocharger, power output and the rest of the exhaust system. 63.5 mm (2.5") is used on many stock and mildly modified cars, while 76 mm (3") is common on more powerful turbo setups. A larger diameter is not automatically the better choice for every car.
Downpipe with or without a flex joint?
A flex joint absorbs some of the movement and vibration between the engine and the exhaust system, reducing stress on pipes, welds and other components. Whether you need one depends on the design of your car and the downpipe, so choose according to the specific application.
Is a downpipe suitable for a daily-driven car?
Technically a downpipe can be part of a daily car's setup, but you must consider noise level, other modifications, software and the legal requirements for road use and emissions. On a daily driver it is especially important that the whole setup is chosen correctly.
What is the difference between RM Motors and TurboWorks downpipes?
RM Motors is the main downpipe brand at Select Parts, offering high-quality construction and models for many specific cars and engines. TurboWorks offers a good balance of price and quality and also has solutions for many popular European cars. When choosing, exact fitment to your car and engine matters more than the brand itself.
