Hi all. I respect everyone's opinion here so I thought I'd lob this question out there for you guys to hit it over the park. I love my busa but I'd like to shave a little weight from her (15-30 lbs. maybe?). URIt showed me his undertail mod and his Akropovic exhaust mod and his busa looks and sounds fantastic. In fact, I think I'd like to do the same things. I'd like to go to the 4-2-1 exhaust but I love the throaty/powerful growl the busa put out. Would the Akro be a good choice for me? Is there another exhaust that sounds similar? How much weight could I shave with that mod and what are some other mods that are available that could also shave some weight? Thanks in advance for all the guidance.
