Slant six exhaust
if its a super six it will already have 2.25 all the way back so just pick a muffler you like...
if not go from the exhaust manifold all the way to the out let with 2.25 with fav muffler...
i have a super 44 on mine and it sounds like a beast lol... on the stock motor i think it had a series 50? flowmaster... sounds great....
