Now u can pull the cats out. A few points. Wiggle the exhaust manifold outward from the engine. If it's not moving u can gently tap it to break it free. There is a gasket under it which u won't reuse and the Eastern Cats come w a new gasket. FYI, the Eastern Cats fit perfectly and the nuts will be easier to see than stock. Where the cats bolt onto the exhaust, there is a gasket sitting in the exhaust tube. The Cats came w new gaskets but I left mine in and there were no problems. It's a pain to get them out and clean the pipe. I pulled my cats out the bottom sort of in line w the exhaust pipe. Once out, I tried to take the sensors off w a wrench but no go. I soaked em in PB Blaster for a day still no go. So I got a sensor socket from Harbor Freight for $5 and that eventually worked. I put the old sensors on the new cats. Installed everything and there was a lot of smoke from the sensors. Crap. I removed the cats and tightened down the sensors. Reinstalled, same smoke. Crap. Took em out, reamed the sensor hole in the cat w a $5 thread chaser made for sensors again Harbor Freight. Smoked again. Crap. Removed the cats yet again and did a smoke test by closing all holes and blowing smoke in w a smoke gun. No smoke. Figured maybe the smoke from the gun was too weak so I blew in cigar smoke really hard. No leak. WTF? I then remembered I put thread compound on and maybe that was just burning off. That was the case. I let the engine run until the smoke from the sensors disappeared and good to go. 6 removal and installs on each side later.
