3.5" Exhaust Pipe Downpipe for Chevrolet/GMC 6.6L L5P Duramax Diesel 2017-2022

$191.39
C138-B034

Feature:
1.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.
2.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.

This product was exactly what I needed for my exhaust system, easy to install and works great.

This downpipe fit flawlessly. There weren’t any issues with alignment from the turbo to the exhaust. The slip on fitment from the end of the downpipe that meets the rest of the stick exhaust was perfect. It slipped right in and no exhaust leaks. I was a little skeptical of the product initially but would 10/10 buy again. The flex portion was actually able to move as well.
