I've owned my 2003 for about 18 months now, I went through various slip-ons before I settled on some Microns. I've got a K&N air filter, PAIR system is removed and a PC3-USB running a generic aftermarket air-filter + slip-on map. Bike ran pretty good, felt proportionately right compared to my Blackbird & VFR800. I also replaced the complete 2003 head with one from a 2006 to fix an oil leak recently.
I laid it down a couple of months back and got some new Chinese fairings which looked and fit great but one the Microns got a few good scrapes so I needed something else. I stumbled on a set of brand new Yoshi's on craigslist for a great price which were simply labeled as "for Suzuki". I called the seller and he said something about GSXRs and when I told him this would be going on a Gen I he believed it would fit perfect. I picked them up and took them home and to my disappointment discovered that they didn't fit. When I looked up the model number I saw that they were for the Gen II. I considered hacking them up to make them fit but decided rather to try my luck finding and fitting a Gen 2 header system. I found one for $30 on ebay and got it all hooked up a few weekends ago. Everything fit fine except the mounting lug behind the sump doesn't match and the belly wing will have to be trimmed a bit to make it fit. It definitely sounded and looked different but I really didn't have much time to play with it. About a week ago, I removed the Yoshi street baffles because it was a little too quiet.
After that long preamble, here's the part that's got me scratching my head; the bike seems to have significantly more power low down in the rev range, and I'm talking about enough that it feels like a different bike. It pulls hard from very low revs too, open the throttle wide at 1500 RPM and it pulls unbelivably well - certainly WAY better then the Microns and Gen I header. I have not removed the CAT in the Gen II header and the only downside I have found so far is that the Yoshi's are cooking my feet.
So is there any good reason that Gen II headers with Gen II Yoshi slip-ons would make significantly more power than the old stuff?
