New to Busa's but not to bikes. Anyway, a question, installed a new set of full black widow exhaust (Gen 2 2008), welds and workmanship excellent, no problems with install, however, 2 things that I dislike, #1, probably can't reach between header pipes (not spread wide enough) to remove oil filter without removing parts of lower fairing & #2, on idle, exhaust doesn't have a deep throaty loping sound. However, performance is way better than my previous slip on's.
A friend of mine hasn't done any engine performance mods & he claims he can change his oil filter without removing any fairing, plus, I have heard his yoshimura tri oval exhaust on idle & it has a deep throaty loping sound like he has a high performance cam. The loping, sounds like my Harley with all the performance goodies.
Don't know if it's yoshimura's header bends or the can inside configuration versus the black widows. Removed the baffles but no change, it just gets louder.
Tried checking on the internet for the sound on a Busa, prior to buying but no one had posted any, so I took a chance @ $517 included free shipping on eBay to Hawaii. I like the stainless steel headers & CF cans, just disappointed in the 2 listed things.
Aloha from Hawaii. The forum helps.
