i was taking off my 2000 exhaust system and i broke one of the three cat bolts/studs? and i tried to beat it out but it would not budge if anyone can hel i would really appreciate it thanks

 

Often, if you heat the flange with a MAPP torch (propane is not as hot, acetylene is better if you have it) the expansion of the metal will allow you to hammer the bolt/stud out. Just be careful where the hot bolt lands... ;-)

 

would it be ok to just leave it would it for sure leak?

 

I'm talking about a MAPP torch that you can buy at Home Depot or Lowe's. You'll find many uses for one over the coming years...

 

yea but i mean would it be ok to just leave it with two

 

it will likely leak with just two studs.

if i were you i would put it back together and bring it to an exhaust shop and have them weld on a new end flange.

 

It would leak for sure....plus it isn't a good place to have exhaust gas escaping. Carbon Monoxide = death or at least sickness.

 

It will leak. I took a ball peen hammer to hammer one of mine out, then went to Lowes and just got a replacement bolt/nut.

 

Mig or Tig weld a nut onto whats left and wind it out. If you dont have welding gear visit a local workshop.

technique is to weld through the centre of a nut onto whats left of the stud. Just be careful not to weld the stud into the flange. After the heat of welding they often wind out really easily.

 

just heat the flange and hit it out
