Im doing my exhaust right now and the three nutz holding the piping to the cat are seized. I pb blasted them to hell two days ago then again this morning and they still wont budge, im trying to find my impact wrench right now does anyone have any tips???

 

Just keep cranking on them. Those were the same bolts that I got stuck on. I just used a breaker bar and had 2 people crank on it. I also hammered the breaker bar with a hammer in the direction to loosen it to give it some torque to break them loose. the top one is a pain in the a$$

 

ok i have a tanabe racing medallion and the two bolts for the center pipe are not there can i used just regular bolts until i get them. What kind of bolts should i be using, should they have the springs like the muffler bolts? shold i just loc tite them until i find something?
