Anyone a veteran of removing the stock cats on a 370z? I need some help because I can't remove those demon bolts. I've tried for two days and failed both days. I have stripped the bolt on the passenger side and the grip-tite sockets that I have can't even loosen the bolts. I'd like to remove the stock cats without damaging them.

I'll treat you to lunch or dinner for your assistance. I'm in Elk Grove. PM me for my number if you have time and can help. Thanks.

I'm willing to meet at your place if you have better tools to get the job done.

 

Did you soak them in pb blaster/liquid wrench, or try heating them up w/a blowtorch?

 

I soaked them with pb blaster two consecutive days. I don't have the others.

 

take it to a generic muffler shop, they will remove it with some heat

 

remove intake piping, get an extension, go from the top. That's how I did it.

 

^^^same here, but the bolt is stripped. It won't turn with any of my sockets.

 

I've stripped/rounded bolts before, and had to rely on these to remove them:

I'm in the Folsom area, and I've removed cats before...once and for the LAST time though...because it was such a PITA! I'll pay someone the next time I have to swap cats! I did it with the car on jack stands ---> big time suck!

 

^^ yep, Ive used those too, work well.
