S4 Turbo manifold questions.
So I recently sent out my turbo to BNR Turbos, and I think that I'm going to remove so bumps and high spots in the casting of the turbo manifold. The biggest thing I notced was a tube inside the manifold. What is it? can I shorten in or have it welded shut and grinded completly flat. any help?

It is the EGR feed as said above. Feeds exhaust air thru the hole in the rotor housing.........passes thru a passage in the rear rotor housing to the rear side housing...travels up the rear side housing to a EGR passage....passes thru the EGR to the intake manifold which has a passage molded in it ....to the the intake air. That's turbo cars. Non turbo is a bit different on a series four.
EGR's are useless on RX engines and do NOTHING for emissions at all. Zippity.

not to thread jack or anything. could you just use 2 front rotor housings to not get that little tube? i've never understood why each housing is different, but if you were to take off and block the EGR, and was replacing the housings, can you just use 2 front rotor housings?.. or am i just talking crazy?
