Exhaust "Y branch" on a pre-cat.

[griffski]

I am about to fit stainless manifolds and Y branch to my standard 92 4.3 Griff.

Has anyone noticed any performance or running problems fitting the gas flowed Y branch? I have aquired the type with the 3 bolt flange and the holes where the Lambda sensors would be are blanked off and welded up?

I have noticed that a stainless pre-cat 8 hole flange Y piece is available and is similar to the original.

you'll have no probs with that. its the after market one long header one that i put on my 500. not sure who made it but i believe its based on the tuscan racer set up.

runs fine on mine and looks good too.
