I do not like the stock exhausts on my 05 dyna and had been looking at the V&H big Shots and others with the same forward sweep from the rear cylinder but was a bit concerned about being able to get easy access to the oil filler bung to check levels and when doing oil changes and it seems that even though they are supplied for this model dyna they would impact on access so started looking at slip on mufflers instead. The two reasons for the intended change is the visual and the sound. I do not like the way the muffler changes diameter at the rear and extends behind the axel as it gives and awkward visual and of course the sound is a bit muted. After a lot of searching and rejecting a lot of options I have got my agent in the US to get me a set of these from Radient Cycles
This is a pic of them on a bike.
I meant to add that I have a set of reversion cones on the way to take care of the decel popping that can occure without them. Will run them with the baffels fitted so it shouldn't be too much of a problem.
