I'm wondering if a custom exhaust could be made that is quieter than the stock unit. It is not known as a free flowing exhaust so it could at least be quieter. I can't find any pictures on line of the innards and wondered what is in there already. Enthusiasts tend to like loud so aftermarket parts are often louder than the original. I'd imagine a custom exhaust could maintain air flow with fewer decibels. Do you have any pictures?
