We have not had the time to do any dyno test against 6.0 manifolds, but we have quite a few customers running them with great success
2000degree coating on 2 sets. Both started new and neither have any coating left on them. Could it be the weather or road conditions? Maybe. But the up pipes are still coated and they were done the same way and time.
i am also curious on the RCD mans and up pipes. Really wish some numbers were out to c if there worth the money
