i have a 4.4 with the X-pipe mod and I am thinking of going to customize my exhaust system.. This time I might cut off the orignal mullfer and replace it with flowmaster and put on some nice tips... what you guys think about this mod?? Im affraid it might be too loud, I am thinking of the flowmaster 50 series muffler with single inlet and dual outlet, so I can have nicer tips welded on...
