ok i just got my buschur catback and im trying to get the cat back off but im having a really hard time getting the nuts that hold the catback to the cat off and the O2 sensor out can someone please help me??! i really want te get my catback on!

 

Spray some WD40 on them and let it sit, also see if u can get a breaker bar. It will help a lot.

 

Ahh yes, I can totally sympathize with this problem.

After spending about an hour of trying I winged over to Sears to buy a can of PB Blaster and the biggest breaker bar they had. Had the two cat nuts off in less than 5 minutes. If you're going to reuse the nuts I'd recommend cleaning them thouroghly with a wire brush as well as the studs in the cat.

Also I would suggest removing the nuts from the cat first then doing the rear of the car (muffler, hangers, etc...)

Let us know how it goes.
