The ISR Performance stainless steel bellmouth downpipe for the Nissan Skyline R32 & R33 RB20DET / RB25DET replaces the restrictive factory downpipe with a 3-inch, one-piece unit that bolts directly to the turbo. Increasing the size of the downpipe allows exhaust to flow more freely, unlocking horsepower.

Before You Order
○ Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
○ Confirming Compatibility
Our entire product database is based on North American vehicles (USDM), so please verify whether parts will fit Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look it up for you.)
If you place an 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 using the tabs on our homepage, this does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All product descriptions 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 Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when placing your order. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air. We do not use sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength study documents or similar documentation for Japanese inspection purposes. Therefore, all parts are sold for "circuit, private property, or off-road use only," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. As all products are shipped internationally from outside Japan, there may be instances of shipping damage to the packaging or products. Please understand that we will only provide returns, refunds, or replacement products for damaged, defective, or incorrect items if you notify us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not work through other companies or distributors located within Japan.
