Good detail without seal.

I like this part but it doesn't come with a seal. So I have to wait another week for the gasket to arrive before I put it on. This is what a week without a truck looks like. Make sure you get the stamp.

Pros
  • Best
Cons
  • I will add later

Great sound in filters

You will definitely notice the difference when you switch from a standard product to this one. It is great. The only thing I didn't plan on doing was removing the top of the plastic harness protector.

Pros
  • Best in its niche
Cons
  • Don't remind me

Works and looks good but very difficult to install.

Installation on a 2004 Chevy 2500 HD is very difficult. Allen had to make an elongated ball. They should charge extra and ship the right gasket and tool. However, after installing it, I noticed a difference. The turbine spins faster. My tuner said that from 0 to 60 also caught. Also looks nicer than the factory. Update: Looks like it might save a few mpg of fuel on my truck. I suspect because it improves EGT and turbo winding.

Pros
  • Nice packaging
Cons
  • Some difficulties
