Re: Stripped studs in exhaust mounting help!
You can buy the supplies needed at most hardware stores. 1/4 20 is available at virtually any place. Check Autozone for a tap kit. I think they have small sets (either metric or standard) that come with 3 taps and a handle for $8-9. A small Ace or True Value will run you $10 for a handle and $4/tap. Make sure to buy a tap handle and cutting fluid as well. If you are not mechanically inclined, I would suggest having someone else help you. Go slow, make sure the tap is 90 degrees to the hole and turn the tap 1/4 to 1/2 at a time and then back it off a bit. You want to make sure that the chips come out.
Your problems will be much, much worse if you break a tap in the hole.
