Look at what I just scored!!!
Boost activated exhaust valve. Starts to open at 9psi. Its wide open at 12psi.
I'm going to install this after the CAT. Then build a 1 1/2" dia. exhaust pipe loop around it pre-turbo that will have a Honda OEM muffler inline.
With the valve closed exhaust will have to run through the muffler. At WOT the valve will open at 9psi. and have a straight shot 3" dia. to the turbo and dump out at the quarter panel.
