The z1 has about 30 more HP than the b6, is newer, and I would say returns better mileage in the same car with the same gearing than the b6.

Headers are the pipes running the exhaust from the exhaust ports into a collector to the cat and out the back of the car, I would say there's no point in swapping headers, and the y8 headers were made for a performance engine, so they're prolly tuned for higher RPMs anyway.
