okay, check it out. I have a 4 door. and i know that the 2 and 4 doors are the same lenght for the cats...I accidently orded the wrong hi flow cat for my car. i got the hatchback one coming. (tell u the truth my dad is the one that ordered it for me...anywho) So now i just wanna know if the hatch one will be the same as the 2/4 door one because I don't want to have my whole exhaust off my car (putting header and catback on once the cat comes in) and find out that it will not fit and have to put the stock exhaust back on.
