1989-2002 Nissan Skyline GT-R Race Master Exhaust Valve - Single by Manley Performance
Race Master, and Pro Flo versions identified as Race Flo valves, are manufactured from XH-426 material for exhaust and NK-842 material for intake. This valve series is intended for bracket, drag, and oval track racers operating at 8000 rpm or below. Generally, engine speeds above 8000 rpm require titanium valves.
Any engine builder who has successfully used EV-8 alloy (21-4N) valves will find this series of Manley valves to be an excellent product at the most attractive price. The ultimate tensile strength charts on this and the following pages show that the Manley Race series is equal to the best offered by the competition.

Before Ordering
〇 About Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm the compatibility with Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether the listed product is compatible with your vehicle. Our support team will check it for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs will be paid at the time of settlement. For shipping estimates, they will be calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping amount and the actual shipping cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow enough time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air freight. They will not be shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation sheets or similar documents for the Japanese system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," so please install and use them at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that we will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt for products with shipping damage, defective products, or products different from what you ordered. Please note that for products sold through our company, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
