if its on the same level as an aftermarket catback in terms of loudness/drone then I dont see why anyone would spend $1000+ on a catback when the gains are minimal.

car sounds good imo OP!
It's going to be a lot louder than an aftermarket exhaust. While the turbos do a great job muffling the sound a bit, they aren't a great replacement for a muffler

Most people get an aftermarket exhaust for both sound and the removal of the rear cats which frees up some HP. Does that justify the super expensive cost for the mild gains? Not really, but if you're in the market for an exhaust, I'd hold off for a bit until you've had a chance to checkout what we've got in store
