Exaust Question

Hi everyone. I'm thinking that sometime down the road I might like to change the exhaust on my 73 CJ-5 with the 258. Right now it has the stock manifold and a a plain 'ol muffler and exhaust pipe, nothing to write home about. I would like to replace the exhaust with something that sounds deeper and has that throaty sound to it. I don't want something too loud, but just something that will give it a little character. I'd also like to keep the stock manifold. Any relatively inexpensive exhaust systems that you guys might know about that will give me the sound I'm looking for?
