First of all I appreciate everyone's help in "schooling" me on the 2011-2012 Mustangs. I know a lot about my previous car but know nothing about my soon to be new "baby". Does anyone have Pypes Violator and H pipe on their car? if so how do you like them, any drone, if so what rpm, is the idle loud? I am looking for an exhaust that has a loud deep idle and where my wife can hear me pulling in to the driveway and say yep Brian's home. I found the perfect setup for this for my old car but cant seem to find that one for the Mustang yet. Also do the 2012 GT Premiums come with an H pipe from the factory? If they do has anyone swapped out the factory h pipe with an aftermarket and get better performance gains? Thanks again for the help.
