Replacing the cat.

Got a 98 (which i hear are famous for bad cats) that needs a new catalytic converter. What i'm wanting to do is just simply cut the old one off and somehow bolt on a new one considering i really don't have access to a welder. My question is, can i do this and how hard would it be? I think i needa 2.5" cat. Is this correct?


I found this cat on ebay. Does anyone think this one will work? Thanx.

You just might have to add pipe if there not the same lengths.

You can buy an aftermarket cat from autozone that you can bolt right on with muffler clamps

Either one will work just fine however, they should be welded into the system for best results. Usually a shop will weld it in for you at a nominal cost.

Weld the cat. on,no clamps.Stay away from the one from AutoZone(really called AutoJunk).The fastest way to cut the old cat is a recipicating saw with a 6'' 18tpi blade.Do not throw the old one away and there is a reason why.The old one is worth some money,$50.00-$60.00 for the old cat.There are guys out there buying them from auto repair shops,auto salvage yards just for the metals inside.
