ok. i am replacing my front exhaust on jeep. but the bolts that go into cat were welded on back side. and they broke off flush with cat. ALL THREE.. how can i get them out?

 

Either drill them out or cut it off!!

 

Drill them out and replace them with STAINLESS STEEL bolts so this never happens again.

 

well i am on first bolt still. first time im drilling out. but can someone gimmi a tutorial.. cause when i drill it is half way done. but doesnt seem to get farther than that.

 

Many times a drill will get dull and you'll have to put a new edge on it. Also when drilling a bolt you will want to drill a pilot hole then go larger and you will want to use plenty of oil. Also drill with a lower speed than if you were doing home projects. Using a drill going fast will cause the edge of the drill bit to dull faster and the extra heat can cause the bit to fail.

 

oh ok. i heard something about left handed bits also?

 

left handed bits are for extracting broken bolts. in your case won't help.

 

If you can get a 4-1/2' angle grinder on the bolt heads, you could at least grind them off so that much less drilling.

Don't forget the safety glasses!

 

when i did the exhaust on my buddies tj, it was all rusted so we cut the bolts out with a recipro saw and just put new bolts in. good luck!

 

no no. the bolt heads are out. and i cut the front pipe off from the cat. now i have cat and rear pipe. but the bolts that were in the front to cat still have the threaded side in them. and there welded from the cats side.
