Race Master Exhaust Valves - Set of 8 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 series of valves is intended for bracket, drag, and oval track racers operating at 8000 rpm or below. Generally, higher engine speeds require titanium valves.

Before placing your order
〇 Regarding import consumption tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇 Checking compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Furthermore, 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. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding delivery
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when 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 cost 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 plenty of time for your order. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding compliance with Japanese vehicle inspection (Shaken)
Our products are generally designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide documents such as strength calculation sheets for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are 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 box or product. Please understand that we will only handle returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Additionally, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
