Features:
1. The up-pipe connects the exhaust manifold to the turbocharger and lets exhaust gases flow in. The down-pipe links the turbocharger to the rest of the exhaust system and allows exhaust gases to flow out.
2. By removing the factory downpipe and replacing it with a high-flow unit, the turbo can more efficiently expel exhaust gases from the turbine, thereby generating greater power. Since the factory downpipe is a performance bottleneck, removing its restriction allows for an increase in the vehicle's boost.

This downpipe is a great upgrade for my 2015 Nissan 3.7L Powerstroke. It was easy to install and improved exhaust flow and engine performance a lot. Just be sure that your engine is 3.7L.
