Thread: exhaust cut-out, y pipe flow

Tweet

I saw on "trucks" how stacey put electric exhaust cut-outs on copperhead. He used a Y-pipe after each header secondary to split the flow two ways. One path led to a cut-out, and the other through the muffled exhaust. I think this is cool as hell and would like to do it, but I'm wondering if the Y-pipe would affect flow and sound when the cut-out is closed. I've attached a .pdf sketch showing the exact layout.

go for it wont know until you try it.

I'm doin it. I can't afford those expensive things now, but I'll have it all set up and ready for when I can.

is having exhaust cut out's on an exhaust something that would make it fail inspection?
or is that just for newer vehicles
