ISR Performance High Flow Cats - Infiniti Q60 3.0T
ISR Performance High Flow Cats are custom-made using 300-cell metallic substrates, which are less restrictive than stock, allowing you to gain power while still converting harmful exhaust gases. ISR HFCs are fully TIG-welded using true mandrel bends throughout. ISR Performance HFCs bolt on to factory or aftermarket exhausts (as long as the aftermarket exhaust is built to OEM specifications). ISR HFCs retain the factory oxygen sensor locations and also add a more aggressive exhaust note.
What's in the Box:
2x Stainless steel high flow cats
3x 2-bolt exhaust gaskets
1x 3-bolt exhaust gasket
9x Bolts
9x Nuts
** All ISR Performance products are designed for off-road use only **
Legal only for racing vehicles which may never be used, or registered or licensed for use, upon a highway in California
Before Ordering
〇 Regarding Import Consumption Tax
At Shaftooya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges other than the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please confirm whether the product can be installed on a Japanese domestic vehicle (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it 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, make, and model from the tabs on our top page, it does not necessarily guarantee that they will fit Japanese models 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 Shipping
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 are rare cases where there is a significant difference 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 within Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. Please note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please understand that they are not adapted to the "Japanese Vehicle Inspection System" at all, and we cannot provide strength calculation documents or similar for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, 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 or the product. For products with shipping damage, defective products, or items different from your order, we will provide returns, refunds, or replacements only if contacted within 7 days of receipt. Please understand that for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
