Seems really well constructed. Sounds great and is good for life. Definitely flows better and RPM goes from 1k-1.7k where the turbo takes over. Install was easy although there are no directions. They will answer if you call them though. They only include 1 1/8 NPT thread for the fitting, if you dont already have an EGT probe you will need to buy another one, which is annoying. I wish I would have put some tape on the ring to remove the heads near the front so I didnt scratch the finish a little. Also, buy some M10x 1.5 studs, 4 of them or so, and loosely put them in so you can set the manifold on them and then play whackamole with the bolts and gaskets. Re use your stock bolts, maybe clean them up a bit. Some anti seize. Would still buy again.

Very well made product.. Fast shipping helpful customer service.. Will order from them again

Very happy with it. Made a huge difference in how the truck drives. Picked up a few mpg too. Boost elbow that was included really helps the turbo spool too. Definitely recommend it

Real good quality

This takes care of the problematic factory design.
