or get some custom 2.5" piping at an exhaust shop for maybe $150-$200 and go with the universal Apexi WS2 Muffler. It sounds the best overall. Or even go with the 2.5" piping with a OBX twin loop muffler. Yeah it is OBX but it sounds great. I got rid of my Skunk2 Mega Power muffler, kept the 2.5" skunk2 piping, and threw on the Twin Loop and it sounds AWESOME. Sounds just like stock except at WOT !!!!
