Not surprised. These things about weld themselves together. Is the DP/cat off the car? If not, take it off - you may need to put your car on ramps to do this - take the thing off from underneath the car. Being creative helps provide the necessary clearance. Then heat the hell out of the cat inlet and start wiggling. If all else fails, and the cat is junk anyway, knock the cat off the DP with a BF hammer. Did I say that? And don't injure yourself or wipe out your car in the process.

BTW, a muffler shop would probably loosen things up for a few bucks, no thrown out back, no smashed knuckles, no burns, letting you take the cat off when you got home.

Took me and a friend all day to take my cat off. Hammer, saw, cutting wheel, nut breaker, more hammering, more sawing. Only real advice is to completely destroy the studs, or it's not coming off.

Yup, I tend to agree it's a bitch of a job - best left to a muffler shop with a lift, a torch, a BF hammer, and a big, sweaty guy with a grey, sleeveless sweatshirt with lots of burn holes, hairy armpits, and a very bad attitude.

No muffler shop will remove a catalytic converter. It's illegal for them, and there are huge fines for it. Personally, instead of removing it, i'd just take a long screwdriver/pipe and a hammer and just empty it while leaving it on the car. You can get a ticket for not having it installed on your car. As for removing it, try a hammer, or maybe heating it up with a torch...

They won't remove it, but they can loosen it for "another time and place"...

I used a cutting wheel and cut several (about 4) slots lengthwise along the cat where it slpis over the downpipe. I then used a piece of metel to help expand the slots and was able to twist/pull the cat off.

This sounds like a good way to skin the cat...

But you'd need a steady hand, and it probably still wasn't as easy as making toast.

I took a right angle 4" dewalt grinder I have and cut one slice parallel (meaning in-line) to the exhaust pipe... on the cat inlet....did it carefully w/o cutting through the DP that was under it..... with the muffler clamp off that was on the cat inlet.... and my one slot.... I shook and wiggled with DP still bolted to turbo... and it came off w/o much of a hassle. It is now home under my workbench..... probably never to be installed again... :wink: FWIW.....The cut I put in it could be welded up real easy after re-installing it if I decided to do that.......
