The best exhaust
But since you are tying to build a ZL-1 knockoff then I would say GMMG is the only option for you.
As far as my opinion on the best exhaust, true duals, hands down. Loud mouth is nice until you get headers. Then, very few of the people that have it like it. It's insanely loud and has a butt-load of rasp.
