Exhaust connection question

[2012Boss302]

A friend has a 2013 Boss and he wants to buy ARH headers with off road X-pipe. Currently the car has a full Magnaflow exhaust from the cats to the mufflers. Here is a link to exactly what he has, https://www.americanmuscle.com/magnaflow-competition-catback-1213boss.html . Question, will the ARH mid pipe slip fit with the Magnaflow over axle pipes????

You'll probably have to ask Magnaflow if the over-axle pipes in that kit are the same length as the stock ones. If they are, there's a good chance the length will work with the ARH headers & x-pipe. The other major issue is diameter of the over-axle - stock is 2.75" and the Magnaflow is 3". However, the ARH X-pipe is 3" with a neck-down to 2.75" (at least for the Boss kit) to fit the factory over-axle pipes. I think you can ask ARH to make the X-pipes without the reduction so they fit a 3" pipe. Doing it this way, you use the ARH x-pipe instead of the Magnaflow.
