That would suck to have a Scion brake light, there goes easy badge swap.
Aftermarket companies will have a dual exhaust.
I'd like to make my own, do a 2" diameter true dual with 2" x-pipe and 2 mufflers. Everything would be 2" diameter and each muffler would be 2" inlet&outlet/5" round body/2.5" tip. Like a motorcycle.
