4WD Turbo RX

The car I have came with 2 catalytic converters, the first hangs vertical from the turbo and then there is a 2nd under the car just past the transmission. The 1st catalytic converter is the restrictor catalytic converter, it was plugged.

The restrictor cat was plugged and problem is solved, turbo is ok and boosts again! Thank all who helped with suggestions and info.

Ok, I have inspected for boost leaks and see nothing wrong. I thought it might be the restrictor cat but exhaust comes out strong at idle and there is no cat beyond the restrictor one on my car, it was removed with new exhaust pipe work. Is there anything that makes the car cut power that I should look into?

I have a 1985 4wd Turbo RX manual trans Subaru. I am not sure why I can't get the car over 4k rpm and the turbo light comes on after 3k but kinda flickers, could I get some help understanding why the cars lacks power. I have great idle, easy cold/hot start and trouble with climbing hills and speed above 45 mph.
