so my new job for the summer involves me driving brand new 2012 and 2013 mustangs and today (my first day) i drove a 2013 boss in school bus yellow with the track key. BEST EXPERIENCE EVER!
i tried he doesn't like it he has a x pipe and flow master american thunder on it already. He wants JBA long tube headers, shorty catted x pipe and borla s type mufflers
i need the loudest full exhaust possible for my friends 2011. He's undecided between borla or JPC. He wants a race car sound and he won't take off the cats sooo any ideas???
