Thanks for your response guys. Vanne I've already spent a few $$$$ and looking forward to spend a few more to make it full bolt ons with a tune and those other little mods that may or may not see additional HP. I know It seems like i'm throwing away dollar bills here but I just don't see myself buying a supercharger (or saving for it), and then doing maintenance on it for this S54 running 102,xxx miles. These mods are just for fun really.
Pokey; definitely need a tune. Starting to inquire with TTFS. As for the Xpipe, I'm thinking Rogue Engineering but I was told that I could simply take the car to a muffler shop, have them cut out the resonator and voila! Any cons to doing this other than losing the OEM resonator?
