Best sleeper muffler
Not only are they packed with a buncha material, but they also have a valve that is mostly closed at idle and part throttle so it's super super quiet. In fact so quiet that all I hear in the cabin is enigne noise and the clickety clack of the valves and lifters.
But when you go WOT, it opens up and it's pretty much a straight through muffler...so loud as fawk.
Best of both worlds.

A good combination is LT headers, good quality y pipe , electric cutout with an aftermarket super quiet muffler or stock muffler from a performance car or even stock muffler from the ranger.
