There are few things as satisfying as mashing the throttle and hearing your engine roar, but since this is a family forum, we can’t really talk about most of the other ones. And while a factory exhaust note is fine for some drivers, there are plenty of folks who aren’t going to be satisfied until their engines sound like a pride of pissed off lions gargling with gravel.
