O3GMC said:A 'custom tune' is where you would call up Allen from Nelson Performance, give him info on your truck and what octane you use, along with your VIN and service code on your current stock PCM....he uses LS1edit to create a custom program and modifies the air/fuel, timing, Torque Management, shifting speed + pressure etc etc.....sends you out the custom tuned PCM and you ship back your core. I believe people see anywhere from 15-25hp from custom tuning. He also offers free upgrades if you mod later on, and a 30 day money-back guarantee.
As far as the Volant and Magnaflow, I'd first search ebay for the Volant (got mine for 250 shipped), or go to www.Tbyrnemotorsports.com - they often have sales going on. You can also get a cat-back exhaust kit from Tbyrne or any performance shop. I bought just the muffler from www.hottexhaust.com and had a muffler shop install it with a turndown before the axle. Mine is the 22x8x11 oval muffler part no. 14579, which I believe is the same one that comes in cat-back kits such as the one you can buy from Tbyrne.
