i agree with wordwarrior on the roadster stock pipes sound, to me it is the best. it is loud enough to sound like a strong bike but civilised enough to not be another harley douche or annoying. this is why i wanted to keep the stock exhaust on after i carpenterised the engine.
but there comes a time when you want it maybe a little louder and definitely want the bike faster. i also wanted to get the cans up out the way for more cornering angle without scraping stuff. so after a lot of 'mad scientist' work i managed to build a custom system that to me sounds the same as the stock roadster pipes but greatly amplified.
also gave me a fair performance boost too.
