They worked. There were put on a SRT6 last weekend. tri-zombie had them put on his SRT roadster, he can attest to the dyno numbers.

15hp/20tq from the headers w/ stock exhaust and stock ECU I believe were the numbers. Jake from Eurocharged can better attest to them.

I know Jake has long tube headers on his C32, but I think they were running into issues with long tube headers for the SRT6.
