The best sounding exhaust on these cars is the GT500 style mufflers. The issue is the volume. Needs to be 2-3x louder than it is. Nicer rolled tips would be a plus there too.
Exhaust on these cars is a matter of trade-offs. Had these Borla S on the car for a bit now. I love the tips. The idle, light part throttle, and WOT sounds good. No drone. Bit louder than the GT500 at least @ WOT.
These things still don't sound great to me at heavy part throttle. There is some rasp there and I am not a big fan of that type of sound. I can't imagine the ATAK series, probably sounds like outlaws but minus the drone. Not sure really but at the cost of buying/selling these exhausts I can't afford to mess with it any more.
Honestly wondering if I could get some aftermarket tips for the GT500, have them welded on, and then I might just put them back on the car and sell the Borla S.
