Needing some opinions on my exhaust?

[Jcaillouette]

I just put a 408 in my NNBS crew cab with long tube headers an a catless y pipe into single 3". I would like to know if it would benefit me or hurt me to run true duals an if it would make it sound any better? Maybe someone could post up pics of their exhaust setups or maybe a sound clip.

so whats sitting on the top of this 408? top end is very important to what the exhaust would need? whats the header size?

[Jcaillouette]

Factory truck intake an headers are 1 7/8

PRC stage 2 ported heads 59cc

my own opinion would be 3" dual even though its a cc
