I have JBA LT Headers and I was wondering if I can install MAC O/R Prochamber midpipes to my Long Tube Headers

 

Look here:

Shows pics of the splice-in, to-stock-cats prochamber, the shorty legs MAC sells to attach that to their long-tubes, and the location/length of their tubes, which are really mid-length. The JBA would likely work fine if you got those shorty legs (someone posted they're about $100 from Mac, call or email them to confirm) and cut them down to the proper length, but I don't know about the flange that attaches to the header itself.

If you get their off-road prochamber, the legs go all the way to the stock exhaust manifold, so you'll want the splice in model with the shorty legs.

Definitely won't be bolt-in, will require some cutting, and clamps or welds to attach everything properly.
