I have an 03 Screw 5.4 and was wondering if anybody has only replaced the stock muffler with a after market one or just simply removed stock muffler and put a straight pipe in its place.

THANKS,,,,,,,,,,,,,

I replaced my stock muffler with a Ravin Z33 SI/SO and added a chrome tip. It has a really nice sound when I get on it, but is not too loud on the highway. A friend of mine replaced his muffler with a straight pipe and surprisingly it's not extremely loud. Neither of us have had any problems.

 

I put 2 Ravin Z33's on my Lightning. They do sound badass!
