Purchased the exhaust adapter kit along with the turbo cat downpipes, you cant have one without the other. At start up I could hear a little growl to the truck and for a 6cyl I was skeptical but was pleasantly surprised, little turbo lag and the truck seems to run smoother/better. AND don't forget the install kit!! I ended up breaking a stud off the turbo so it was nice to have that kit on hand, well worth the cost. Thanks Offroad Alliance for the help and advice
