RE: Removing mufflers
I've been mufflerless for six mobnths or so and at first it was great, not a lot of drone, not really loud unless STOMPED on hard, but it has since become too loud for me. It sounds awesome at startup, but giving it half throttle makes it sound as if you are trying too hard. There is also some drone on the freeway that I didn't notice at first.
