What's a good sounding, louder than stock replacement muffler? I got to hear Dee's with the Magnapack system and it sounds great, but I don't want to buy a whole new catback. I've tried to just buy the Magnapack mufflers, but Magnaflow doesn't seem to offer them that way. It was also mentioned the regular Magnaflow's were quieter than our stockers, so don't want to go that route. I have an O/R X-pipe, so probably not Flowmasters since they sound best with the H-pipes. What other options are there?
