So, I've had my '93 Spider Veloce for a couple months now, and am really enjoying it. However, I must say I'm quite surprised at how quiet and docile this thing sounds. Looks like all of the exhaust componentry stock, but I still expected a little more tone out of it. Is this pretty normal for a series 4 spider? If so, what exhaust systems do y'all recommend to get this thing sounding a bit more 'Italian'???
