Better yet, cut the cat off and either put an after market one on, or splice a straight tube in place. You would be surprized what the recyclers will pay for that little cat. Probably over $50.00 on ebay. (Last I checked)
Here's my true story. I parted out a samurai. I went ahead and took the exhaust off but hadn't cut the cat off. You usually cut it about an inch from each end and take a picture of it with a ruler by it and say how much it weighs. Then say something like 95% full. (How someone figures that out, I don't know but that's what people say when they list them).
I took the picture of it still in line and listed on a Sunday evening. Got up Monday and cut the ends off with my Saw-zall . Low and behold, the Catalytic converter was empty.
I was pissed. Then I realized that I had to run in and remove my listing before someone bid on it. Oh well.
