Cool Installing Armytrix - vacuum source ? Have question


So I've narrowed it down to either the Akrapovic slip on exhaust or Armytrix - although I have concerns about the Armytrix (see below).

I like the ability to open and close valves using the Armytrix...but, in the install instructions they point out the vacuum source to tap which is near the throttle bodies.

I worry about effing something up tapping a vacuum source there, I'm sure others have done so but still worried it might muck something up later on with car.
  • What bothers me and creates cause for concern is that in the install guide for the E9X chassis they show the wrong type exhaust for the E9X chassis.
  • There are also present in the exhaust shown actuator valves which don't exist from the factory exhaust unit.....these all point to a sloppy install. So what does that mean for overall satisfaction and quality of the Armytrix exhaust itself if they cannot even get the install right ?
