im trying to remove my back section of exsaust(sp) bc i think my muffler is stoped up bc im getting back pressure and i cored my cat but anyway i cant get the 3rd bolt off the connection what size are tehy the 1st one broke up with a 14mm and is now stuck in the socket the 2nd 1 i got off wit a 13mm and the 3rd is to big for a 13mm but 2 small for a 14mm Help plz im bout to go kill my rex

 

having worked in a muffler shop, the bolts buy heat and rust get smaller with age..... another option is that someone has already taken it off and replaced the bolt with a standard size.... try a 9/16 socket

 

tryed that 2 big umm would u try to file it down to 13mm and then pull; it out or just cut wit off wit saw and replace whole thing?

 

what i would do is just disconnect the exhaust at another point drive it and see if that is the problem.if it is then go with the irreprable damage .

 

lol i ran out of breath reading that.

 

If you can get a hacksaw on the bolt, cut through it.

 

vice grips

 

I had to use a dremmel with the cutting blade when I did it. It was the only thing that would fit.
