you should have 1 5/8", some big performance heads run 1 3/4" header tubes. Job will be easier if you have access to an air impact and some long extensions with a universal or swivel.

ok thats what i thought the only bolts givving problems are the h pipe where headers connect to them cant get them loose other then that is there a way to get it out without undoing the header and hipie bolts?

1stStang

No, you have to unhook the h-pipe from the factory headers to get them out of the car.

u have to take those bolts off where they meet

driver187
