Title: Catalytic Converter Q?
Post by: jcsanders79 on January 17, 2009, 01:05:39 PM: I need a new catalytic converter. Looking for feedback on the "high flow" aftermarket ones. Should I buy a random technologies, magnaflow or just get what ever is cheapest at the muffler shop? Its a 97 with a chip, header, CAI, bored TB, TBS, ford injectors and an electric fan.http://

I guess not, but it's worth asking... My cat sounds like a jingle bell, so I am guessing something's wrong with it, and I want to go the high-flow way (magnaflow, to be specific).

On a YJ it's bolt-on. Two bolts on the front and a clamp at the back. I've had mine for years with no leaks. It's also easier if you're replacing the rest of teh exhaust or you've already gone with a cat-back that is clamped on.

I'm pretty sure mine was welded on when they did the crappy wok on the exhaust (they fixed most of it free of charge, but I am not sure they fixed this). Guess I'll have to take a look andfind out next weekend...

Post by: Jeffy on January 20, 2009, 07:31:37 PM: I like mine bolted on so that when it gets damaged, I can easily remove it. Not to mention, my Cat-back has a lifetime warranty which I've had to replace on a few occasions. Clamped properly, it won't leak.

TJ's have and a few different setups. I think the earlier ones are bolt-on while the later ones are welded to the head pipe...
