cherry bomb turbo mufflers and What size pipes?

[moparsons]

Anyone ever run cherry bomb turbo II mufflers? I'm wondering how they sound/perform. I was given a couple from a friend of mine who took them off an elcamino to go with glasspacks.
   Also....I'm getting ready to put dual exhaust on my 69 Dart (reason for question above). What size pipe should I go with? It's a stock 273.......2 1/4?.....2 1/2?

I have run them and they sound ok. Your pipe size should match the inlet size of the muffler. I would think 2 1/4 would be fine for a small block.
