Headers are installed Need a recommendation on Muffler

I've heard a lot of things too over the years, "very difficult" being relative. First hand feed back is always more accurate.

If you want to quiet it down, add a vibrant ultra quiet resonator and a 15x8 24in magnaflow or pick your brand and do the largest body muffler.
I havent added headers yet but yet but this setup has near a stock sound level but with a growl

I've installed headers on every year coyote mustang and on an 18 5.0 truck. It's not dificult, Maybe a little time consuming but the truck i'd call easier than the mustang's. Truck you can at least get at them through the fender wells to get better angles.
