I've heard that cat removal is the way to immediate large performance gains. Do those who have done that agree? Looking the job over, I see two options. Cut the cats out, preserving the welded Y and the flanges to the turbos, and fit and weld tubing in between the stubs. The second option preserves the factory assembly by removing the flanges and Y-pipe assembly and replacing with new flanges and custom pipe assembly.
I suppose the cats can be welded back in later if it became necessary to restore originality. It seems the easier approach. How did you do it?
