NPP Install

The NPP mufflers are about 500 each from gm they will bolt right up the the h-pipe you have on your car or yuo can add a x-pipe.
The vacuum tubing and solenoid and all the vacuum parts were around $250-$300.
And the Wireless Exhaust controller I make that has 3 operating modes, Full open, user selctable Rpm open and Full closed is $200. I also have four other models that range from $75-175 dollars.
I love this mod. It gives you the best of both worlds!
It took me a weekend to work slowly and install the mufflers, vacuum tubing and solenoid and wire in the custom controller. Its sweet!
I have the full parts list and diagram of the vacuum piping on my website at www.sunsetorangecreations.com in the how to section.
Exhuast conrtollers are in my online store at www.shop.sunsetorangecreations.com
Pm me if you need any info.

BenGreat info Ben.
I'm assuming that the check valve at the manifold is to prevent any backfiring from blowing apart the vacuum system...
I don't see any inline filters to keep dirt out of the manifold in case a vacuum line comes off or apart (perhaps integrated into solenoid assy?). You would think it would be near the manifold tap to give the most protection though. Perhaps integrated into parts 001/002?
