Why Upgrade Your Downpipe?
If you're chasing more power, sound, and throttle response from your turbocharged engine, then upgrading your downpipe is a must.
A stock downpipe is often one of the biggest restrictions in your exhaust system. Swapping it out for a high-flow or catless alternative immediately improves turbo efficiency, reduces backpressure, and brings your car to life.
Whether you’re building a full Stage 2 setup or just want to unlock the real sound of your car, a performance downpipe is where it starts.
The Benefits of a Performance Downpipe
Upgrading your downpipe gives you:
- Faster turbo spool
- More aggressive sound
- Increased horsepower and torque
- Lower exhaust gas temps (EGTs)
It’s one of the most effective mods you can make for any turbocharged platform.
Pair it with a tune, and you’ll feel the gains instantly - both on the road and the dyno.
High-Flow & Catless Downpipe Options
We stock a range of downpipes to suit different driving goals and emissions requirements:
- High-flow catted downpipes - Less restriction, with emissions-friendly setups
- Catless downpipes - Maximum power, sound, and flow (track use only)
- Heat-shielded & coated options - For reduced engine bay temps
Each downpipe is designed for plug-and-play fitment, using the factory mounts and hardware with no cutting or welding required.
Downpipes for BMW, Audi & Mercedes
You’ll find precision-fit downpipes for nearly all platforms including:
- BMW M & M Performance models (M2, M3, M340i, etc.)
- BMW X models (X5, X6, X5M, etc)
- Audi S/RS models (S3, RS3, S4, RS5, etc.)
- Mercedes-AMG platforms (C63, E63, A45, etc.)
Be sure to double check the emissions rules in your area before purchasing.
Finish your build with these mods
To get the most from your downpipe, pair it with:
- Valved sport exhaust systems
- Cold air intakes
- Upgraded intercoolers
Together, these mods form the foundation of a proper performance build and work best together to really get the most of our you car.
