Can anyone recommend an exhaust system for my 383 Dart?

I'm building a OE numbers 383 GTS and I just got the Factory Head pipes and Tail pipes from Don's Custom Exhaust in Ohio. They are 2 1/4 pipes which is alright for me since I needed to use the stock heads and ex manifolds. I did use a much better camshaft and made some other rather Stealth upgrades also. I just looked up the correct size mufflers for it and decided to go with the Dynomax Ultra Flow #17512. Still need to procure the correct tail tips tho. Will install all this this week sometime. I'll post an audio of it then.
