I made one myself. I had a small piece of aluminum that I didnt need. Traced it to the same size as the gasket and drilled two holes in it. It bolted right up w/the gasket. Then I ripped out all the EGR crap - vacumm lines, etc. I dont have a custom chip/modified ECU either. No problems here. No real seat of your pants feel in power gain, but it does assist w/working in the engine bay. Very easy to remove all the stuff. You will need a few rubber caps to cap off a few vacumm lines - got mine from AutoZone, like a dozen for $2 or something like that. Really cheap. Im in Kansas, we have no emission laws either. Just try not to rip stuff up or break stuff, just incase you have to use it again later.
