An aftermarket muffler will just sound different.
In MOST cases, provided the muffler is NOT a restriction (its NOT on the TJ), changing the muffler will do nothing but sound differently.
If you want the catback system, it will change the sound again (being that again, the exhaust on a TJ is NOT restrictive).
If you want a drawback, it could be the sound if you dont like it (too loud, too much drone, etc), otherwise it shouldnt do anything negative.
You MAY even get a SLIGHT increase in power (not enough to make it into a speed demon or anything, but any dyno Ive seen from a TJ exhaust is very minimal).
