Quiet exhaust?

[iroc22]

Im trying to find a muffler for my Grand Cherokee which has the 5.2 V8 and I want something that is quiet and free flowing. Ive been looking at Dynomax Super Turbo, Magnaflow welded, Edelbrock and have been considering others as well. Im thinking CRF will be the quietest but Id like to see some input from others

Just to let you know, the system is a single exhaust which is completely straight, no weird ass bends like an Fbody ha
