For anyone installing the system: The install sheet that shipped with the systems from Magnaflow were written after their first tear-down of the car. I worked with them this week to get a bit more detail included in the instructions, so here is a revised version:
The original instructions don't mention extending the vacuum lines to the valves; we include 2 sections of silicone vacuum tubing and connectors so you can make the connection to the valves and still have plenty of slack to tuck the tubing out of the way. If you don't need the extra tubing to make the connection to the valves just go ahead and disregard that part of the instructions.
The installation is actually fairly straight forward, the hardest part is removing and re-installing the under body panels and diffuser.
A Public Thank you to @JoeCab for holding my exhaust until I get back from Europe!....my wife will want to know "WHY are you anxious to get back to work??!!":wink2:
