I also like the Harley air filter. But I do tend to think the Roland Sands is a total tossa (right up there with OCC Senior) so I'm a little biased.
The ventilator is a decent enough stage 1, the RSD would be close to it, doubt you would notice any difference between them performance wise at stage 1.
Black and low profile is my aim also. I went for the S & S mini teardrop and Bassani Road Rage. Both super easy to install, hardly worth paying someone to do it. A lot of other pipes I looked at were much longer, hanging out past the rear axle which I didn't like.
nice! the pipes look exactly what I was thinking. I like the tail tidy as well
Tail tidy is a must! I fabricated that up the same day I picked up the bike because I couldn't stand looking at it.
