Just got my OFH installed, it is wonderful! For those worried about sound:

I've always been the kind to see guys ride past in loud fartcans and wonder "the hell were they thinking?". To put it mildly, I was very anxious about the loudness of going with a catless header.

Adding OFH made it maybe 20% louder at idle or light cruise. You can tell it's modified, but it's not obnoxious by any stretch. Cold start changed in tone but really wasn't too much louder. The biggest change is when you step on it -- it's quite a bit louder then, but that's when you want it to be loud!

This is with stock OP/FP and a P&L catback. P&L's is one of the quieter catbacks, it changes tone more than it changes volume.
