Welp, gave up after about 30minutes of little to no progress, called up a shop, drove the mufflerless FiST there and had them knock out the studs for me in all of 5 minutes, cost me $40.
So, today I put on my map exhaust, Pierce front tower strut brace, trunk brace, eibach rear sway bar, and a no-piston's evap canister skid plate. Not bad!
Pierce 2 point tie bar and rear torsion beam stiffener go on next. Then we're getting the intercooler, AP, and skipping straight to stage 3 custom tuned! Wee!
