Dual exhaust

[UPS]

I have a 1986 Chevy short bed that is getting a GM performance parts ZZ 502 deluxe crate engine with headers.
It has a TH400, NP205, Dana 60, 14 bolt.
I am wondering what size dual exhaust I should put on the truck. I was thinking 3", does anyone know of a 2 1/2" or 3" kit for this truck? Part #'s would be great.
Has anyone used one of the universal street rod kits from flowmaster or dynomax to do this, if so which one is best?
Which mufflers should I use? I want some that sound good but are not too loud driving around. It is ok if they are real loud when I get after it. I read the Dynomax super turbo mufflers flow good and aren't too loud. What do you think?

All suggestions will be appreciated.

Thanks,
Mike

I have the LMC set up and I like it sounds good. Not to loud but has a nice throaty sound.

All I saw on LMC's website is 2 1/4" exhaust, did I miss something?
