Weird. Mines pretty throaty at higher rpms. Guess that's what you get for $350, a mystery
The main issue I have with it is the fitment. It's good, but I'm a stickler and the tips being a little off will drive me crazy. One is a hair lower, and they're both centered but more towards the inside of the cutouts.
May pay the shop to cut and weld to get it perfect, but I still may opt for a more what-it-should-have-been-from-the-factory sounding Borla or something.
Just so other people know.
