Just curious..on the Flowmaster cat-back are the tail pipes from the muffler 2.5" or 3"?....Who besides the Borla has 3" tailpipes? Looking to go back to Y-Cat-Back...But maybe cut and turn down before the pipes get to the bumper. I like the no tips on the SS...Maybe Corsa or nothing..

pretty much all the catbacks are going to be 3" pipes, unless for some reason they are stock size at 2.75"..why ya going back to y-catback?

Who here likes Mufflex?....and I am going back mostly for clearance for a drop, and to tone it down inside. I think true dual sound amazing though!

most cat-backa re 3 inch but then the tail pipes reduce down to a 2.5 or 2.75
