Cat bolts

Bring it to a shop and can it a do it. Let them deal with the headaches of the install chances are you'll encounter... just watch and make sure they give you YOUR stock cats back, I live in NJ and brought it to the hood they did a great job but had to cut out a bolt, good install but they wanted to keep my cats so they gave me different cats that were not mine, I went and spoke to the owner they had a "mix up"

Whether you do the work yourself, or take it to a shop, just remember to remove the O2 sensors BEFORE tackling any of the bolts, especially with an impact wrench. Otherwise, most likely, the sensors will get damaged.

This is wrong, I hear this a lot and its a myth.

Back in the day when there was resistor type 02 sensors, they would get damaged from impact wrench's. This day and age they're a heater type 02's. They still have a resistor, but completely different style.

I own a exhaust/mech shop, we never remove the 02's, ever.

Inless there a resistor type o2.

Really? I've heard a lot of people here report failed O2 sensors after shops use an impact on them. If it's a myth I've wasted a lot of time doing things the hard way.

Yep, We had to prove to one of my mechanics that this was the case.

we brought in my shop truck , took out a 02, smashed it with a hammer a bunch of times, put it back in, worked perfect lol, 2 years later. still working fine.

I see a lot of shops when installing 02s they don't back whined the wiring, they install it and twist up the wiring, the pin usually pulls out of the 02, and then its fd.

Hmm. Thanks for the info. Learn something new every day.

Wrong bud. The impact WILL KILL the O2 sensors.

Been there, done that. You've been lucky.
