Can anyone tell me what the standard exhaust sounds like on the Barchetta?. I was looking at either getting a new back box made up for my current system or just getting a whole cat back standard after market for about the same price. (£130 ish on ebay). I don't mind a sporty sound when pressing on, but I don't like the boominess of mine (2-3500 revs), which dominates everything and is a bit out of character....Especially when I might just want a quiet pootle down the country lanes and villages.....Any exhaust opinions welcome - is it possible to get a nice sound with just a centre and back box, and is the standard system so rubbish its not worth bothering with?....
