the ppe pipes i ordered sept 1st are FINALLY en route. should be here Friday or Monday. how much did you guys pay to have them installed? i went to see one of my wholesale customers, and he said about 8 hours. he was looking at the exhaust manifold removal and reinstall. to me, and I'm not mechanic, it looks like the car gets put on a lift, remove 6 nuts and bolts up front, 4 nuts and bolts at the back, remove, install, reinstall hw. i would have guessed 2-3 hours MAX.
