Crazy Exhaust Idea

**Flame Suit On**

using the stock vacuum line and valve to make an ECS????

anybody know what -psi the exhaust valve opens at?

I was thinking move the valve up to an X-pipe in the exhaust and just extend the hose. i know its probably really pointless, but i guess just think of it as any other pointless exhaust that's out there in the market. quiet at low rpm/loud at higher

I know, i'm crazy but its just a really random idea that has come to me at 2am.

like a vacuum controlled cutout? i don't see why not but i'd rather have it controlled by a switch, might as well do one right after the headers
