Funny you mentioned this. I had the same thought when I read "dip"... I had ProPipe on my 95" and it made great power at higher RPM, but dipped hard. Makes for a goofy dyno chart too, D&D guys got nothin on this dip... I pulled it and went to Swinefart true duals. (I say that with fondness as I miss those pipes.) Yeah I lost the big numbers on top, but really liked that set up.
