ISR Performance HGC LS1 S13/14 Swap Headers are made of high-quality 304 stainless steel and are designed to be paired with our proprietary LS1 swap mounts for easy installation into your S-chassis.
Constructed with 1 3/4" piping, ISR Performance headers provide excellent flow for high-horsepower applications.
The new and improved "HGC" High Ground Clearance LS Swap Headers are designed to provide the best possible ground clearance. To ensure proper fitment, ISR Performance mounts must be used. Due to the new design, some floorboard clearance around the 2-bolt flange may be required to accommodate engine movement during operation.
What's in the box:
- Driver side exhaust header x 1
- Passenger side exhaust header x 1
- 2x Header gaskets
- 2x 2-bolt Y-pipe gaskets
Legal only for use on competition vehicles which may never be registered or licensed for use on public roads or highways. May also be used on other exempt vehicles.
Before Ordering
〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Confirmation
Our entire product database is based on North American vehicles (USDM), so please confirm compatibility with Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product will fit your vehicle, please feel free to contact us. Our support team will investigate 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 on the tabs of our top page, it does not necessarily guarantee that they will fit Japanese model vehicles without modification.
All products are 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, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. 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 order with time to spare. If you are in a hurry, please contact us to confirm delivery times in advance. Please note that all items are shipped via air freight. They are not shipped via 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 adapted to the "Japanese Vehicle Inspection (Shaken) system" in any way, and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-public roads," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if notified within 7 days of receipt. Also, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not coordinate support through other companies or distributors located within Japan.
