Feature:
The downpipe on your turbocharged vehicle is directing the exhaust gases out of the turbine housing into the exhaust system. An aftermarket downpipe will typically be larger in diameter and either uses a high-flowing catalytic converter or remove the catalytic converter altogether.

By removing the factory downpipe and replacing it with a high flowing unit you are allowing the turbo to more efficiently move gases away from the turbine which creates more power. Since the factory restrictions are now gone you can increase the boost on the vehicle as the factory downpipe is a choking point for performance.

Racing down pipes

Arrived in good time and packaged well! Supplied with everything I needed to bolt straight onto my car. Good quality and well worth the upgrade from stock exhaust. Made with a much better flexi so shouldn’t have the problem of them failing like the standard ones suffer with. All in all 10/10!

Great pipes. And great fit and great sound

The install wasn't to hard. It was easier because I was catless on my audi s4. Shipping was very fast and the pipes sound great
