My muffler is about to start being religious( holy in other words ) So I am looking for something that would make the TJ sound a little different. 4.0 inline and its awful quiet, I miss my YJ that had little to no muffler and the roar it could make, however calmer heads ( in other words the lady of the house) has said No your not having a window rattler like that!I was thinking flowmaster but if you guys have some suggestions I will take them.
