The orange is the gasket and yes you do.

The silver tube is the EGR crap and you should look up details on how to properly remove it. You will need block off plates, a plug for the hole in the intake, and have the codes for it tuned out.

You can simply pull it out and cut the long tube off if you don't want to remove the entire system at this time.

EGR = Exhaust Gas Recirculation. It pulls exhaust from the exhaust manifold, and recirculates it back through the intake. It is for emission purposes.

Will I get any hp from deleting the egr or does it help the car run better with no hot exhaust gases going into the intake manifold?
