After being on jack stands for 2 months and about 7 hours help from echocanyons (thankyou

)my car is finally on the road again, sort of. I have an exhaust leak on the #3 because of a broken stud

. It's about 1/16 of inch below the hole. I think I am done wrenching for a few months and I just want it fixed quickly. ANy guess as to how many hours labor (worst case) to get it out? I figure 1-1.5 hours for HE and Muffler removal, maybe 1-2 hours for bolt removal? @ $85 hour about $300 clams
I am tired and ready to drive it. What can happen if I drive it around this weekend with the leak? Burn a valve?
Any input is welcome (positive only please LOL)
