blackduc238 - like that Laser exhaust, it's better than my Remus. They're lighter too. I also agree with the recommendation to run it with it's chip to realize the full benefit.

Your brakes are fine, you can easily get air under the rear wheel coming out of straights with what you have. Stainless steel brake lines, HH pads or better with high temp brake fluid and you're in business. I do also like the Braking rotors but I've had friends who have no problem getting air under their rear wheel with stock rotors, which in your case should be 320mm, not the earlier 305mm. If you have ABS, you're not getting air under that rear wheel. But I do wish I had those 6-piston calipers on Gus' bike, nice.

On the cylinder heads, if you have the later bike (i.e. 2004?, 2005 for sure), you have the longer suspension, including forks (from the GS?). I'm guessing they are around 5mm longer which should do the trick in keeping your valve covers from scraping unless you go down. Aftermarket shocks are the ticket, stock sucks in comparison and the aftermarkets are re-buildable. I'll bet there are members on the board who know for sure. I have extra valve covers, has been cheaper to do this.

As for using the GS intake tubes, I'm pretty sure they will NOT fit with your SJBMW air filter (they need to reside in the same volume in the air box). They are also really for midrange (street over track). I have a BMC filter with mine for my tourer, not using them on my project bike, that bike will be running above midrange on the track.

Just my 2 cents, hope it helps.
