Just put a P-log on my GP. Wow, I don't remember the front exhaust manifold being this easy on my Impala. Maybe took me 90 minutes, tops. "Hardest" part was finding the hole to put the oil tube back in the engine block. 7 screws off, kept the engine lift bracket off permanently, and putting said bolts back on. Oh, and the two crossover bolts, too. I only PB blasted the crossover bolts - exhaust bolts moved fairly easy. Now I just need my wife to move her car so I can "test" it out.
