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.

We worked on the truck getting it deleted all weekend and the last thing needing to be done was the exhaust and it was completely wrong!

Empty

Says order fulfilled 14 days ago I guess they meant the money was taken 14 days ago. No email or contact. Only a shipping label created and the shipping company doesn’t even have the package yet 14 days later.
