Any chance you could post some pictures?ibrowse said:nr133... I've heard the Xccelerator 2:1 system for the first time this week. They sound AWESOME!!! Low rumble on idle, then BAM when you hit the throttle! "Ahhh yes, the Harley sound preserved!" They are finished MUCH better that the Thunderheader with the full heat shield assembly. Additionally, they perform at least as good as the Thunderheader, if not better; the reports I have reviewed on dyno-testing indicates the Xccelerator 2:1 out-performed the Thunderheader by a decent margin... Probably is why they cost a bit more, but do not require heat shields, etc. Mine get installed on 12/13/02 along with the high-flow Screamin Eagle and standard jetting kit. I actually called the DG Hard Krome company and got to talk to a technician. Of course, they raved about this system up and down! Shall see! I will let you know how it all turns out shortly.
