SERboy, Group5 Motorsport, 8268 Miramar Road, San Diego, CA; (858)693-3278. I bought mine from them last summer; at the time AEBS headers were in stock and hotshot headers were not. Also, AEBS had just finished retrofitting the headers w/ EGR ports. Group5 was prompt in shipping; thorough in including the right hardware (a nut/plug for the AIV port, extra wire for the O2 sensor).
Go for it. It's not cheap, but it's worth it.Two tech-heads who have seen my header both said it was really nice and well-built (one of them is an old school V8 guy who makes custom headers).
Hope this helps.
