Ethan Vargas This up-pipe works great! Easy to install and fits perfectly. Definitely helped with improving exhaust flow.

Terry Hailey Engine runs smoother and sounds more solid. No more strange noises from the front.

Sherry Had a nasty exhaust leak on my Duramax that was driving me crazy. This manifold and up-pipe combo was a lifesaver. Came with all the gaskets needed, which was a nice bonus. The fit was spot-on and after the install, the truck is so much quieter and feels like it's breathing better. For the price, it's an solid fix that feels like it'll last.

Oliver Deeper sound without being too loud.
