Rating: (see review/s)

"At first I had some trouble getting the rusted bolts off but an oxy-acetylene cutting torch made quick work of them. I have access to a lift and made this install 10 times easier. I recommend taking this part to a shop or somewhere where they are used to working on exhausts so that you don t ruin any other parts like the studs on the manifolds. The left side manifold part of the new cat did not fit correctly and I had to drill the holes bigger. But after a couple of hours we got it and the pick up is running great and running very smooth." posted by: Hiluiman on March 26, 2014
