04CHASE Posted April 2, 2011 Report Share Posted April 2, 2011 not true on sound , that all depends on muffler your running after the cats. it can sound great with the right muffler but depending on your setup it may get more drone. if your boosted , do not use the magnaflows they will melt and magnaflow will not stand behind their product. i was one of the first with the 59559 or similar part number on those cats . they do make great decoy's though.
