When pushing your Subaru EJ207 or EJ257 to the limit, exhaust gas temperatures (EGTs) can become a major concern. The GSC Power Division Super Alloy Exhaust Valves are designed to handle the extreme heat of high-boost, high-power environments. With a 33mm head diameter (+1mm over stock), these valves optimize exhaust scavenging, allowing your turbocharger to spool faster and your engine to maintain peak power throughout the RPM range.
These valves are a must-have for any high-performance build where reliability is non-negotiable. The Super Alloy construction ensures that the valve head maintains its structural integrity even under the most demanding racing conditions. By upgrading to these precision-engineered components, you are significantly reducing the risk of valve failure while simultaneously improving the overall efficiency of your exhaust port. Experience the difference in quality and engineering with premium components from GGCRACING.
