If you are talking revs and a speedstar ECU then you have another whole issue on your hands moneywise. You are now mating the components to make the most of each individual part and you are gonna plop down some serious money on internals. Ask Oliver. (Or the above and original "fastest m.f. on a warrior", Monsieur Underdog.)
For me it was a delicate balance of worth equalling value. If I put something on the bike that was negated by not putting another something on the bike, then it was money wasted. When I went for looks, I lost speed --- when I went for speed, I lost comfort --- when I went for comfort, I lost looks. On and on, ad nauseam.
The argument over pipes will read like a novel but most agree that the V&H 2-1 is a jewel. I run Shogun Shorties (just cause I like 'em) and had my PCIII mapped for the quarter-mile to match. By the way, be careful with powdercoating your pipes; black will tend to "yellow" with some applications. I prefer low-tech BBQ paint and it is extremely durable.
Oh, and one more thing, if you have a local track close by, you are one lucky man. They just closed our local track to build a subdivision... I am f'n heartbroken.
