if you could design an exhaust system

I remember reading on here somewhere that Jake said the most power he saw was with cheap headers, high flow cats and stock muffler. I keep thinking about getting a set of OBX headers OBX Exhaust Header Manifold for Porsche 986 97-04 2.5L/2.7L/3.2L Boxster and a set of Circuit Works high flow cats Circuit Werks Porsche Boxster 986 2.7L 3.2L High Flow Cats Catalytic Converters | eBay I just haven't pulled the trigger yet. Last year I actually bought a different set of $150 headers. The quality didn't seem very good so I sent them back. The reason I haven't pulled the trigger yet is, do I really want to spend $550 on something that wont make any real gains? Not to mention a lot of people had issues with the bolts on the original manifolds stripping out. I had my stock muffler ceramic coated black last year, so that is staying on the car. I also don't want any drone. By the way my car is a 98 base with one set of O2 sensors, 2000 S muffler W/ Crios mod.
