2013 Mustang GT Flowmaster Outlaw Catback + Headers + Midpipe

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?

I believe you say you already have the catback exhaust. This means you have either the x or h midpipe with over axle pipes and then axle back pipes/mufflers. I would assume these bolted up to the stock catted pipes that go between the midpipe and the stock tri-Y headers.

I seriously doubt that the midpipe that you have now will connect to the American Racing Headers because typically you should use a matching midpipe from the header manufacturer. Then possibly the American racing midpipe will connect to your existing over axle pipes. You need to contact American Racing Header manufacturer or distributor to confirm. Anything is possible with the right amount of money.
