My truck was sitting at my mechanics shop last night when a crack head with a sawzal cut off one of my two cats. Can I just cut the other one off and straight pipe to the exhaust system? And how do I trick those O2 sensors downstream of the cats into not throwing a check engine light . Any advice would be much appreciated.

Damn crackheads are going high tech. Im not sure but I think I saw vids online with some sort of set up to "fool" the o2"s. It almost looked like a sparkplug type setup that your 02 sits in. That being said aftermarket cats aren't that expensive like a walker brand from Rock Auto is like $100. I don't think I'd cut the other one off

Does you mechanic have insurance for stuff like that. Maybe he'll cover it

I agree with Tommy.
See if the shop will cover it. Unless they have a disclaimer regarding thievery

The shop should cover it, and replace it. Nothing sounds good straight piped, nothing.

A disclaimer would be worthless for the mechanic. Usually a parking garage would have them so they are not responsible if you leave your vehicle unlocked. If you leave your keys with a mechanic that responsibility shifts to them.

parking lot type disclaimers wouldn't even apply here since a part was taken that in no way could have been prevented by the owner of the vehicle while it was in the mechanics posession.

I looked and pushed them to straight pipe it but they said it was too complicated to fool the down stream O2 sensors and that it wound be too loud. 500 for an installed used cat and they actually sent it to another shop to do the work

Yikes, I think I paid not much more than that for a whole new walker set up. manifolds back, 2 cats, muffler etc. Stock is probably better though

Tommy J

Sorry, I meant pre cats back for my set up

Did your walker setup fit correctly? Mine did not. The part where the cat connects to the crossmember is off by several inches. It hasn't posed an issue but I don't daily drive mine.
