Full cat delete flowmaster
Ok so I have a 2004 F150 FX4 with the 5.4 v3. I've recently cut out both cats and both precast for best flow running straight pipe with no muffler and 4" tips true duels. Well that was like Daytona at idle so I put in no name muffler and its sounds stock that was better than getting pulled over every mile. My question is I want a more aggressive muffler but not too aggressive. I was thinking of the super 40 or 44 or maybe another brand that sounds good doesn't have to be flowmaster. What are everyone's opinions on what muffler to run. Any advice would be great. Please keep in mind the muffler has to be a duel in and out.
