I've got an '06 Pony-package that I'm about to install the Pypes SFM65 dual exhaust system on. I'll be using a set of GT take-off mufflers. I've got the stock hangers for the mufflers and have made sure that the holes in the hangers line up with the factory mounting points in the frame; but, I've noticed that the driver's side mounting holes are not tapped for screw threads. Is this the case with all '06 V6 Mustangs? If so, I guess I'll need to use a tap set to make the threads. It appears that the stock bolts are M8x1.25 metric. Just wondering if anyone else had run into this?
