I've never heard of them either, but that's what the shop that ordered them said they were. They reminded me of FLPs that I've installed on C5s before except the cats (very small) were welded in the pipes instead of them being clamped in like the FLPs. It wouldn't surprise me if they were made by Dynatech like FLPs and just labeled for someone else. I even googled American Racing Corvette Headers and came up with nothing. The install only took about 3 1/2 hours anf the fit and finish was really nice.

Here is the before and after A/F. The leaner one is after. The battery was disconnected during the install so I don't know if that would have effected the A/F or just the headers themselves leaned it up. The car was not driven. It was dynoed, the headers were installed while still on the dyno, (above ground dyno) and then redynoed.

i helped install the headers and got to drive the car before and after the headers it made some difference in the mid range it pulls very hard all the way to 7100 but ther will be more to come.... 2xls1 doing the tuning and possibly some juice we will see!!!
