ok so today i notice the cat down pipe to the manifold was a little loose so i tighting it and and snaped the stud in half....so now what how should i go about fixing it any tips would help greatly.

 

heres what I did.

Bought new exhaust bolt and nut
Removed Exhaust manifold.
Could not remove exhaust bolt
Put it all back together without changing a thing

If it doesnt leak dont worry about it.

 

it does leak though and makes a squeaking sound lol other wise i would do the same.

 

Just drill it, tap it, and fit a new bolt of your choice. Tap set at HD is fairly reasonable, better yet HF if you have one close.

 

drilling it what kind of drill bit it.how long would that take

 

You get a bolt extraction kit that comes with everything, drill included. Those studs are not so hard and easy to drill. You may be lucky and have enough stud left to grip it with a vice grip, soak it with penetrating oil like PB blaster and work it loose. You could also just take it to an exhaust shop and have them do it.
Get new studs, nuts and gaskets at DAP http://www.dap-inc.com/ and replace everything, it's pretty cheap. You need a new exhaust manifold gasket set if you remove the manifold.

 

thanks so much guys im going to drill it out today.
