When I bought my pipes I talked to Frankie himself on the phone, he was very up front about the turn around time on these since they were made to order at they time. I actually asked him if there was any way to put a short baffle in them and he was willing to try If I wanted. I opted for the cones which I ordered from J&P cycles, I had used them years ago when I had a Swift Bar chopper with some FTW pipes and they worked good then too.
