Not really a reply but still sticking to primary tube size for headers I was wondering if anyone has some input on Kooks stepped headers. I am looking at their 1 7/8 stepped to 2" with a cat delete system. My thoughts are this will be a good setup when I get the funds together for an FI system.

I would ask Doug at ECS

I have stock rockers no rebuild, you have to look at your dyno to see were to shift at and log it to see what your shift extensions are then pic the shift point

When you shift to the next gear you want to be in a good long power range the dump and dataloging can show you the right spot. Mine is 5800 so if I shifted at 6600 I might be at 5000 on the shift extension

I've got 2 inch headers on my C5 and they are not only a PITB but I know my car is down on power in the midrange running 27 pounds of boost. I'd run 1 7/8's for a blower car over 600-650rwhp all the way up to 1000-1100hp. Anything NA and I'd stick with the 1 3/4 like Dennis said.
