Reasons for the Titanium Q 1. Weight savings would be nice, especially weight on the top. 2. Considering my bike is red sticker, I dont want anything too loud that will draw unwanted attention during green sticker season. Reasons for DR.D 1. I've heard lots of good things about it, especially that you feel gains througout the powerband. i hear the DR.D is really loud, though ?....and it's stainless steel so it must be a good bit heavier ? any thoughts ? ? ?
