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 use 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 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.

Great product!!!

Direct bolt on fits like factory and you can’t beat the price. The install was extremely easy and super fast. It also has a way better sound aka louder turbo whistle.

Wow! Thanks for the pics!

lbz duramax downpipe

It seemed like it was good quality, the welds and bends were clean. It installed way easier than the factory one. I would recommend it to anyone who dosent want to spend a bunch of money and still get a quality product.

Hello. Thank you for your comment! We look forward to receiving your feedback pictures!
