All that R and D and this is the best closed valve sound they could come up with?
People really need to simply keep a stock rear and add HFC/catless xpipe. That truly is the ONLY exhaust to be louder when accelerating but sound stock with zero drone when cruising with no boomy/bassy sound anytime.
You always come off angry and a bit like a know-it-all. Lighten up. OP is proud of his new purchase, and rightly so. Also love the implication that Evolve, who is highly respected here and across the pond, would put out "crap."
