Welcome to our forums,
I know this is your first post so Im not going to give you ahrd time for reviving a 7 year old dead thread.
Toanswer your questions the reason many drivers would like a quiet car is the same as the reason people want soft seats and AC, Just because we drive a fast car doesn't mean we need our eyes, ears and butts assaulted by them. Quiet and or reformed noises are a marker for quality, Thats why many high performance cars have very well tuned and refined exhaust systems. As people grow up we find that refined volume is better than raw noise.I like the un-equal length header rumble but that doesnt mean I need to bend a straight pipe up through my floorboards so I can hear it all the time.
I do not intend to launch a personal attack but often times the excessive volume presented by hondas and harleys makes people look desperate for attention. If you like loud then please enjoy your loud parts but forcing others to listen to your loud parts and inhale your straight pipe fumes is not considerate of others. //hippy rant// Straight pipes are not the best, back pressure is a crucial component of a properly tuned turbo setup and performance CAT also goes a long way towards keeping our breathing air clean and keeps corrosive gasses out of our atmosphere. //end hippy rant// As evidence many international rally organizations require at least one catalytic onverter and on some rally preped vehicles you will find a honey comb catalytic converter affixed to the very end of the exhaust system.
We dont intend to make our cars sound like a Prius, but there is plenty of middle ground between straight piped V8 noise and an electric car.
