The condition of the exhaust studs is what will determine how much cursing will be involved. I got the old exhaust off fairly easily, I found using 3/8" air impact alternating between forward and reverse worked the best. But the studs were done, they twisted off like they were plastic with very little torque applied. The tool from Stomski Racing to drill out the studs worked great (drilled out 8). I messed up one, that was repaired with the Stomski/Time-cert thread repair insert kit, uses the drill out jig for alignment.

One thing I had happen that I've not seen anyone mention is that I had air injection port threads rip out installing the plugs on two ports. Again, a Time-cert thread repair came to the rescue. I actually used their Big-cert that has thick enough wall for the plug copper washer to sit on and seal.

I also replaced the studs and hardware with titanium. Moto RSR on ebay has a wide selection, I got the closest length for the exposed part of the stud and cut the end in the head to suit. Decent hacksaw blade or die grinder and a bit of file cleanup was all that was required. I used normal nuts, no inside hex like stock. The titanium nuts are slightly smaller at 12mm, the 1/4" socket I have just fit through the access holes in the SSI's. A 1/4" drive swivel socket worked for a few more. There was a couple I ended up just using a wrench on, last two inside on the passenger side if I remember correctly.

Got a set of big crow foot wrench for the oil lines. I had the commonly reported fitment issues with the engine cross over oil line.

Every nut, bolt, oil line connection threads etc. got a coating good quality anti-seize... I plan to own the car long enough that I'll be the 'next guy'!

Good luck!
Ross
