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.

No more overheating from the old EGR setup

Excellent craftsmanship! The welds are clean and even, and the material feels high-quality. The 2.5-inch diameter was a perfect fit for my Q50, and the installation was straightforward with no modifications needed. It looks OEM+ and adds a more aggressive touch.

For the price, this DPF delete race pipe is an excellent value. It provides a noticeable performance increase, better exhaust sound, and cleaner engine operation without breaking the bank.
