I have a 2002 GT stock shorty headers and I have a drivers side exhaust leak right at the header and block. I can see the carbon build up already, I've tried to tighten them but had no idea what size bolt it is, and what would be the correct way/tools needed to do this. If there's already a write up I applogize, I searched but no luck. Thanks ahead of time for any help.

There actually manifolds not headers, generally the bolts don't back out from the factory, there actually studs with a 13mm nut on them. Chances are you have to replace the gasket.

Going through the fender well makes them a tad bit more accessible. But yeah, like he said you need a new gasket.
