Not Ranked
Better late than never, but I've used several pairs of Classic Chambered's in the past several months. I'm not sure of the muffler's you had on there, but on my SPF, the difference in sound is amazing. Factory mufflers are meant to pass local sound restrictions and cater to the general public. If you really want to get the most out of your motor, start with the exhaust. Otherwise, you just trying to exhale through a straw.
Dyno comparisons later this month.
