Hi all, Im still fairly new to modifications and I dont know if this question has been asked before or not but here it is anyways.

I currently have the Flowmaster Outlaw Cat back exhaust on my 2013 Mustang GT and planning on installing headers and mid pipes (or whatever other parts are left to have a full aftermarket exhaust system).

Im leaning towards the American Racing Headers Long Tube Headers 1-3/4" With Catted H-Pipe 3" Stainless Steel as Ive heard good reviews about them and that they make a low rumbley sound in contrast to a raspy one.

Will these parts fit together? Or does the Flowmaster Outlaw Cat back already come with the X-pipe? if so what is the part between the X-pipe and the headers that have the stock catalytic converters?

 

ARH headers is an awesome choice, made and fabricated in the U.S. These, Stainless Works and Kooks are the only header sets we put on our cars.


What you'll need to do is use the x pipe that comes with the ARH headers to avoid any unforeseen modifications. The x pipe from ARH will mate up to the stock Cat back or pretty much any other aftermarket cat back.
