2013 silverado 2500 gibson exhaust
sounds great and looks great too.installed in the drive way in a hour.also put a Volant cold air intake on witch gave it even more deeper tone. people look when in going buy. there is no gas change at all still getting the same as before. best exhust and intake I have bought yet as far as sound goes. autoanything gave me the best price on these addons. and shipping was fast. they are great to deal with.
