What does a downpipe do?

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.

Down pipe w/ passenger side up pipe

Can't beat the price point. There was an issue with the up pipe which was resolved quickly by Spelab. Downpipe was easy to install and fits much better than the factory down pipe.

Thanks for the review!!!
