I got the D&D 2-1 exhaust a few weeks ago and now that I've had some time on the bike with the pipes I have a few observations.
By butt dyno alone, I've noticed that these things do really pick up some hp on the top end, and really do lose some ft lbs on the bottom end. This was expected but not bad at all. In fact, it makes the bike lots of fun to ride. It's like a rush to get to the rev limiter and the bike revs much much faster. I need a higher rev limit!
They sound weird, almost like a combination of a two stroke and a diesel truck. The low rumble of the preds is lost for a raspy smooth scream. It doesn't sound much like a twin anymore, almost sounds like a rotary engine. At idle the bike is very quiet, almost too quiet. This remains true up to about 1/4 throttle, but once you open the throttle they scream bloody murder.
My biggest/only complaint: They are too damn low. I've got to get some longer shocks on my bike or figure something out to get some more ground clearance, I scraped them a few times today and the pipe near the collector is getting ground down from making comtact. No good! There will definitely be no riding over speedbumps, off curbs, etc like I could do before. Ground clearance is severely limited.
As much as the ground clearance thing bothers me I dig the pipes. I'm looking forward to getting them on the dyno to see what hp I gained/lost with them.
