twin scroll removal exhaust mani
So when i ripped the emmissions off awhile ago found out i did something wrong. Twin scroll for the exhaust manifold has the vacuum line attached to the uim nipple with a check valve in it but I removed all the solonoids. So technically I guess the twin scroll is disabled (not working). Anyway I rebuilt my hybrid last couple days and while im in here I was going to weld up the bung on the exhaust manifold since the twin scroll is not working anyway. Will i gain slight power 1-2hp by removing and welding the bung because its straight flowing instead of having a flap there? went to the fc3spro to check before posting.

The flow path will be smoother without the door in the manifold, but guessing at some 1-2 hp gain is kind of pointless. All anyone can really say is that it's better flowing.
You'd gain some real power/torque below 2700 RPM if you make the twin-scroll system functional again. You don't need the emissions rack to do it; it's just a simple solenoid setup that you can mount anywhere. It just needs a vacuum source.
