| Ok, I anwsered my own question. The 2460 headers do not come with air hook ups, but I don't need them. They do, however, come with o2 sensor spots. Also, they are shortie style, so they should be easy to install.
Now, an even bigger question: I have the Flowmaster Y pipe 2 1/4" to 3" on order, will that work if I weld a pipe to it then a 3" single back to my catback.
So, my exhaust will go 2460 hooker shortie headers, into colectors, into 2 1/4" duals, into a flowmaster y pipe, out into a single 3" pipe, back into my flowmaster muffler, then duled out into 2 1/2" outlets.
Sound like a good system?

That's the worst combo ever thought of. All you will be doing is wasting money on the 4" exhaust system, plus if you don't have the output that requires it, chances are you'll be disappointed. Either use the Edelbrock's and a good 3" cat-back or get the long tubes (if you have a serious motor that needs it) and the 4" mufflex.
