Dropped by GMR today and got my Dyno scheduled for Nov 12th. I know Steve likes to use the standard HD flared type exhaust gaskets, but I wanted to make sure whether to use those or the D&D provided ones and he said the flared style. So off I went to HD and bought 2 sets of them, $7 each - ouch! 
Got to go on a 4 day trip tomorrow, so will change the pipes out sometime towards the end of next week.
Also, Steve cranked up his 124" bike for me to listen to.....

The tapered gasket does not provide the contact area that the flat gaskets do.

Yeah I can see the flared being a PITA, they do not slide over the top edge of the D&D at all.

So D&D supplies the cometics ( the gasket in your pic) ? They're great. I've even took my Fatcats on and off a number of times and not changed the cometics. Never a problem.
Alan I'm glad I never sold off my fatcat. It's back on and I have no reason for anything else. Absolutely like it better then my road rage II.
Be prepared they are loud. But the sound is addicting.

Steve(GMR) said the D&Ds would be loud too, but I think my 1D5250 Bassanis are pretty loud so we'll see...
Thanks for the vote of confidence on the Fat Cats, I am nervous - a fair amount of $$ to hopefully improve performance.

When I bought my d&d it did not come with gaskets so I used OEM ones. Those in the pic look good though.

Alan, Those are cometics.
No need to be nervous about the performance of the Fatcat. I've compared against a couple pipes now. Fatcats rock!
Look forward to your impression of the pipe when you get it installed. BTW my fatcat is a pain to install compared to others. Very close fit. Just take your time...
