what happened is the pipes feeding into the muffler broke loose, rest of system in exel. cond.,all thats needed is the muffler but since I'm sellin it I want a cheap one, either Bosal or Ansa, the Bosal is about $139 and the Ansa I'm not sure of, my question is Ansa is touted as a "free flow", is it much better than Bosal in flow/power? Since I"m sellin soon, don't care of long term. Anyone know the price of early 6 muffler(<80 633)from Ansa?
