so i bought someone's stock uppipe to gut, so I could have that done BEFORE i had mine out... that thing is unbelievable! i'm not sure how much swearing and hammering you guys needed to get that cat out, but I'm not having much luck... I even got really creative after about an hour, a couple drill bits, and I think my drill. I took my trusty MAP gas powered torch and stuck it down the opening for 20 minutes or so. Then a quick douse with cold water, hoping for a miracle. (the cat exploding...) I think i just heat tempered it or at least just made it mad, it is even harder now!!!
