exhaust and performance
I have a 2001 roadking with stock air kit and hooker tuned flow slip-ons.My bike started popping at the end last season so Im thinking screamin eagle breather kit ,K&N and power commander.Is the power commander a waste if I have a breather kit.Also is there a after market pipe which replaces the Y pipe and will accept a slip-on to make it a true dual set up.Would love some feedback

RE: exhaust and performance
There are a lot of true dual headers out there. Samson makes a decent set for not a lot of coin.
The popping you are hearing is the backfire after unspent fumes reignite and create the sound. Due to the louder, less restrictive exhaust you hear this, where as on the stock system the baffles kept the noise under control.
Personally I am not a Powercommander guy (I have seen 3 fried ECMs in my life, all had PCs on them. Coincidence maybe, but maybe not) I like the V&H product (fuelpak)
You MUST do something with the map if you put a breather on it... it isn't a waste, it is a necessity.
hope this helped a little

You mite need to retorque your slipons, they tend to loosen up over time. They could be sucking alittle air. As gunter said if you go with stage 1 you will want to put some sort of fuel management system on it.

RE: exhaust and performance
Might I suggest an Arlen Ness Big Sucker Stage 1 air intake (chrome) and let your dealer do an ECM/Fuel download from the factory (assuming it's fuel injected?) Tons cheaper than an aftermarket fuel mgt system. If you plan to keep your slip-ons and the "cross-over" you don't need one. That'll solve all your ills. Worked for me and my Rinehart slip-ons. When I do true-dual in the future I'll go with a Power Commander. Rinehart offers slip-ons for those on a budget, then you can get the rest of the exhaust system with the oxygen ports and it elliminates the y-pipe & crossover. You might check if Hooker sells the header pipes to convert you to true-dual.

Performance? Good gas milege, easy start, not much poping etc are all important. If you want to be the badest bike just forget it, its a money race. I think all of the well tuned RK's have great performance and can stand 'true duals" for the sound (just because I like the sound). The "tuner box", in my opinion, should be able to change the cylinder timing individually and fuel mixture for each individual cylinder; the latter being required if the bike has the ability to adjust the mixture indiviualy. The tune should be with fuel to air ratio measurements as well as a dyno to measure the actual power. In most cases, more power less MPG.
