Welded EGR cooler (Scoop out?)

My EGR was deleted by welding the input and output exhaust ports on the cooler.

There is a scoop in the up pipe where it attaches to the rear of the cooler that is now just an obstacle to exhaust flow.

How important is it to either cut out the scoop or replace the pipe with one without the scoop? Would this be a significant benefit?

Unless you have a highly tuned monster engine just Leave the factory up pipe on and attached to your welded egr cooler.

Drive it like you stole it, Or I will.

If your signature block picture is bigger than most peoples post, maybe it's time to fix it. I suggest you tape a photo of your truck to your computer screen, then it only screws up your view.

I would get that scoop out of there. With that cooler blocked off and the original gasket and clamp still on the up-pipe those hot exhaust gasses will get directed into basically a wall. It will torch that gasket like it's nothing.

I agree that without the scoop, the exhaust air flow is perfect. With the scoop in place distorts the exhaust air flow, possible trapping heat in that area and against the weld. But I personally choose the stability of keeping it there.

SIN: are you saying that it will leak at the clamp thru the metal gasket? I'm always learning new things from you guys!

Id like to veto those opinions... previously before the delete while the egr valve is closed your exhaust faced the exact same flow restriction. The baffle left in there will have no negative implications. Also the pressure bottleneck is at the turbo not the diversion plate imo.
