I am considering an exhaust change, but I just put on the OEM panniers (from Sport Touring Accessories) which will stay on the bike permenantly. My questions are: If I go with slip ons, (I'm leaning towards titanium, or stainless) does oval have an advantage over round, will oval fit? What are the pros and cons between Staintunes, Blue Flames, Jardine, or Erions? My goal is to keep the exhaust quiet as possible (stealth mode so as to not draw attention from "The man") with gaining torque, and losing the weight of the OEM cans. If a "Ti Force" or "Akropoviac" full system (4 into 1) will clear my panniers will it be much louder than stock?, is the oil filter still accessible?, will the center stand still be usable? I really don't want to remap the FI because I have no jerkyness or bucking what so ever. Staintunes claim no jetting or computer work is necessary. I don't care about gaining top end (when I blew around a fat tire HD at 148 mph indicated, I had a shit stain in my skivvies), meaning this bike is faster than I'll ever need. This is an 02 Bird with a completely stock engine. Opinions please!
