I just bought a used 2006 Mustang GT with Mac ceramic headers. I just had a Saleen supercharger installed and have been on the gas a lot lately. Now it seems the headers have an exhaust leak.

Does anyone know the torque spec for the header bolts? Anyone have any tips or tricks to get to the hard to reach bolts with a torque wrench? Should I replace the header bolts with Stage 8 locking bolts?

Right now my Mustang has a Mac axle-back exhaust, Mac ceramic coated headers, Steeda panhard bar, Steeda panhard brace, Eibach sway bars front and rear, Ford racing springs, Ford racing struts/shocks, Stop Tech big brake kit, Dynamite sequential taillights, Kazera KZ-A wheels (8.5 X 18 front 9.5 X 18 rear), BFG g-force T/A KDW 2 tires (255/45/18 front, 285/40/18 rear), Redline hood shock kit,
Steeda aluminum pedals(incl. dead pedal), Chin spoiler, Rear 3 piece spoiler, Hood Scoop, Upper side scoops, lower side scoops, Rear window u-shape trim, and a racing stripe kit.

Thanks!
