I have searched this site and a few mustang performance parts dealers and still haven't figured out if anyone still makes these or if I just have to buy an old original pair. Any help would be great.
I order from CJ all the time. If you wait till wednesday you'll get free shipping. Wait until the weekend and you'll probably get 10% off. That's when they run their specials.
All the parts houses have these, Glazier Nolan, NPD, California, etc. I like the repros better than the typical used ones, since the used ones are usually the C7 service/upgrade item, while the repros are the C3/C4 style, without the smog notches in the gasket flange. The repros also have a performance advantage. There are core support "bumps" on the originals, which appear on the outside, and on inside at almost the worst possible place for exhaust flow. The repros have these on the outside only, since they use more modern casting techniques. You can see them here on cylinder 1, 3, 5, 6, & 7:
Also a large price advantage to buy the repro's. Its not unusual for the K code crowd (I hang out with mamy of them) to pay $600 and up for nice originals.
Mustangsunlimited sells them for 249.00. Right now they are having a Christmas special on all their mustang parts...10% off. They ship very fast, I just bought a set and had them within 4 days.
