There's no place in aftermarket headers to attach the secondary air pump hose. You are right about the cat Massey, that's why I got a high-flow cat along with the headers. When you change your exhaust to a better flowing one, you will lose horsepower with the secondary air pump. However on a stock setup it's best to leave it in place.
