For those of you who did a cat back system. How did the old system come out? were you able to pull it straight out the back? I am asking because I have it in a garage, and I only have about 2 feet on either side of the vehicle to work with. If it comes out by swinging it sideways, I have to know, so I don't try and do it in the garage. Thanks in advance!!! BTW, I went with the K&N FIPK, and the Gibson SS Cat Back. I am just waiting for them to arrive!!!
