I had to remove my cat this last week. The thing came apart at the weld. It is OK I just need to weld it back in place. I purchased a Delete pipe and what a difference. I had to pull my 5th wheel from Va. to Pa. last weekend. We are going to Tybee Island and then to Disney soon. I will have the converter in the back of my truck for me to put back on if something happens. The turbo spools up much faster now. The new found power was nice but my fuel gauge told me to stop it.
