I want to know what comes in a catback exhaust I come from the subaru world and I never owned a mustang and will be picking up a 13 gt tomorrow and I do not like the way the stock exhaust sounds. I will not mod heavy till the bumper to bumper warranty runs out. car only has 7k miles on it and im picking it up at 25k. any ways the catback exhaust does that include the x/h pipe or is it just till the pipes reach the x/h pipe? want to order this today and have it come in before Friday or on friday.
