Wish this was around when I did my BSD. It was kind of a pain to do. Had to loosen the bolts on the trans. to get the oil pan off. Just loosen the compressor and set to the side, definitely don't cut the belt. There are ABSOLUTELY no increases in nvh (I was running a CPE RMM and TTR PSMM at the time of install). I may still look into this. Just a little info, if you do the BSD, it will take another 1qt of oil. Exactly 7qts if you use the 400s filter.
