What can i do to the SS Exhaust port Runners to help them flow better?

Chris

 

check out the thread on "custom manifold pics" There is alot of info there that pertains to what you want to know.

 

Why?&nbsp Those stock sleeves are on 500hp-600hp 13B's...how much power are you looking to make?

What stock SS sleeves? And yeh i'm after 500rwhp.

 

The stock sleeves appear to be made out of stainless steel.

 

For N/A PP engines i take out the sleeve and welding a 7' tapering from the inner port to the outer port (gasket) I´ve seen as much as 20-25% more flow with these mods so why shouldn't it be better with a turbo engine to?
