HMF makes a QS1 pipe that is no where near as loud as the regular HMF. Still great power gains as well. Sounds like the pipe for you.
As for air filter, I would go with K&N but I hear the UNI filter is just as good. Then for jetting the bike see if you can find a deal on ebay but other companies sell them as well. Sometimes you can save some money if you buy the whole kits. I know highlifter.com has some good deals. Dynojet is the brand most people run.
