Never heard of that stuff, can you find it in any parts store?

 

you can find PB blaster at an auto store im sure... u can get it at autozone for sure.

 

PB Blaster is the shiiiiznit. its saved me from hours of stress and lists of swear words.

 

PB blaster did the trick on the front 2 bolts for me, but the back 2 were just impossible! i took it to a shop and had them loosen the back 2 bolts and the o2 sensor.

that... also saved me hours and a ton of curse words! haha ... or even more than were already said..

 

did you actually buy a gator grip or did you borrow it from a toyota owner.
tips i have fro exahaust removal:
1) clean exposed threads with wire brush
2) deep penatrting oil (dura lube // wd-40 // 2n1)
3) tighten just a tad before you loosen
4) heat
5) tapping (not whaling) with small mallet
6) use only 6 sided socket OF THE CORRECT SIZE

repeat steps 2-5 as often as nessecery
