Are Flowmax Exhaust systems any good?

Ok. Well I think I have very little if any drone with the Dynomax ultra flow.

i cut out my stock muffler and welded in a flowmaster 40 series, and i 100% love the sound. at highway speeds, you can hear it, but it is surprisingly quiet with a nice rumble. it produces a very good low tone, and no drone. most people hate flow's because of drone, but i love mine. if someone offered to trade me a similar corsa system even to it, and to do all labor of swapping them, i would turn it down. different strokes for different folks.

I like my Flowmaster 40 Series on my truck.
