1998 gmc jimmy catalytic converter replace/install

Here are pictures

This isn't the type of job you would want to attempt. You may be able to bolt on a "direct fit" replacement but if you check the exhaust specialty shops, they can usually install one and everything for less money.

Well, I called serval place in my area. They want to charge $250 to $280 for a univerisal one. I saw several "direct fit" on ebay for $150 to $199. Maybe if i give a shot I can save money. thanks.

OK, but don't be surprised if it ends up costing you more in the end.

My apologies, the concept of changing one out on my truck is easy, but getting those bolts off are murderous. So I found a exhaust shop that charge me about $200 for univerisal one, like you recommended, and i was in and out in 30 min. Job looks professionally done and no check engine light. Thanks for help.

That was my whole point. Glad you got it resolved.
