Down Pipe Bolt Size

[Quicker1]

Having the worst time ever trying to change the head gasket in my 06 GT. The front head is done but I can't get the rear head off. I dont know the bolt size for down pipe. Any help?

just need to unbolt the rear exhaust manifold. its all 13 mm bolts.

if you need the end studs removed its a 4.4 socket or 5.5 not sure witch one at the moment.

re use the exhaust gasket to the head.

How do people keep popping head gaskets?

You must have really really cooked it.

DP bolt size is either 13mm or 15mm.
