Motorat, thanks for the update...now you've got me itching to install the new filter and breather that's been sitting on a shelf in my garage for a month. Any quirky things about the install or pretty straight forward? I'm looking forward to gaining the toolbox. Either way, I agree, I'm really liking the way the D&D sounds on my bike too and I'm happy with the purchase...but i'm in WI, so it's been pretty cold for riding lately, highs only around 40 F.
