i absolutely don't support any idiot who thinks "noise is not an issue" because he "kinda likes loud pipes" knowing full well that the biggest threat to this sport is excessive noise.
A recent article I read in MXA calls BS on your engine mods statement. They got the greatest performance increase from a pipe, with decreasing results as they tried cams, h/c piston and re-maps. So it would seem that the op's original desire for a new pipe, increased noise aside, would be the logical next step and best bang for the buck. And he doesn't have to tear down a motor unnecessarily. Granted, the test mule was a crf250, but I am sure the results would be similar on the KX. And the newest issue of Dirtbike has 3 of the pipes the op is looking at tested on a KX450, so he can get the info on those right there.

Edit: how is the "new" version any different? Judging from FMF's website, it appears they changed the sticker and possibly darkened the anodized blue. the part # remains unchanged so I'm assuming changes were merely cosmetic, or so I hope lol

Yeah, but they are a full race system rated at 98 db+. At least the ones on ebay. You could go Leo Vince X3 or Motoworks for the same price and have something that has replaceble inserts for sound. In Cali, some state areas sound check.

The PC and FMF pipes are both great. I run the FMF 4.1 RT w/ Megabomb header for moto and the Powerbomb header for off-road along with two different FI mappings for each condition.
A few shops usually have the FI calibration kit and will remap the ECU for you for usually around $50 or so. You can also just mail the ECU to a place like Precision Concepts and they'll remap it for $69. They've done a bunch of testing and have good maps. That's what you're paying for... lot's and lot's of testing. It's a 5 minute job. AS Racing has a drive-up FI calibration kiosk at his shop in Santa Clarita. Now that's cool.
Don't some of the pipes come with a means to do the remapping yourself?

Not to my knowledge. The Kawi FI mapping kit is $400 alone of you can get something like the Dynojet Power Commander: http://www.powercomm...ng_default.aspx

I was planning on getting a header and powercommander for my street bike, first, but after this...........
Keeping the stock pipes is sounding pretty good about now. LOL
ANyway, the sound is not a concern for me. I don't give a rip how loud it is, to tell the truth.
I was merely wanting the best priced pipe that gives the most overall power increase thoughout the powerband range.
From what I"ve read, I was leaning towards the megabomb FMF. ???????????
