Mark - I believe he means the LPR mod with the reg coming out of the front and the hosing back to the solenoid - the AA's tried it, I think they used Sledgehammers on their impy's at first.
So it's a matter of still using the second inline after the Armie.
Basically How - the LPR mod is completely unrelated to your air system - the pressure already goes through a second reg anyway.
