68 dual exhaust?

My 68 (327 2bbl) coupe has the original single exhaust on it and desperatly needs replaced. I dont want anything real loud or raspy like most glasspacks that ive heard. I would like a deep mellow sound but not too far off from original. I also want true duals. Does anyone have any suggestions, and keep in mind that i only have about 400 to spend.

check mine out. I have a big block 454 with headers and flowmaster 44 series exhaust cut-outs on my 68 but you can hear it if you would like. The exhaust is true dual and was $300 for me

hope that helps!

I've seen that before on youtube. That ride sounds fricking sweet! What size are your pipe's? I'll be puting just about the same setup on mine in a week or two... 3" for size.
