Default open headers vs. cut offs

Let me run this pass you guys, my 3600 lb street chevelle runs very well, it has fresh 540 Nyes BBC init. I drive the car on the street so I have exchaust cut offs directly off the header collector. They are the unbolt kind not motorized. They are 3 inch as is the exchaust. At the track I open the cut offs and put front and rear tires on the car. It has a good set of headers on it 2 1/8 inch to the collector. My question is do you think the cut offs are enought or should I modify the exchaust to drop out a section so I can run the collector or header open. Has anyone every tested this or had experience or an opinion on this. Let me know Thanks
