A must have for my Duramax. Really improved the bottom end. Auto anything had a sale and was the cheapest I could find. I went with the metal bc it just looks 10x better. I went with an outerwears prefilter as well. I gave it a 4 out of 5 only bc they're still so expensive.
Great addition to the Jeep!

Install was not bad at all. Love the sound coming from under the engine and I can feel the performance boost. The added acceleration is awesome! Have not noticed any fuel economy boost, but probably that is because I accelerate very quickly all the time.
