At the moment do to very high estimates the VHR flange version has been put on the back burner. Also sales on these headers are way more than expected due to increased performance. So far the highest we have hit on our dyno with the Z1 shop car is 356rwhp and 284tq. If other shops aren't making numbers they need to dig into the tune a little better.
