SLP Headers
SLP sells some nice, clean-looking plug-and-play X-pipe headers for about $1300. I was wondering how this might work for a 2012 GS(6M) with the NPP? Where would the vacuum line plug in if stock mufflers and if so would the pressure open the butterflies earlier?

Correct me if I'm wrong, but the NPP vacuum line plugs into the back of the intake (not anything header related). Adding headers should have no effect on this setup.

Not a fan of slip-fit rear end flange-less headers, since they are pain to seal them to the X pipe connection without ending up with a exhaust leak between the two.
