Sikky headers allow for a perfect drop-in fitment for BMW E46s equipped with a Sikky LSx (LS1 / LS2 / LS3 / LS6 / LS7) swap kit.
- 1 7/8 inch primaries and 3 inch collectors made of high-grade 304 stainless steel
- Pre-installed V-band flanges (clamps and mating halves included)
- New gaskets and bolts included
Installation Notes:
Proper header installation requires the use of aftermarket eyeball arms (rear mounting point for the lower control arm) and a Sikky low-profile steering shaft. Learn more about the Sikky low-profile steering shaft.
All Sikky chassis-specific swap headers are designed to be used with Sikky mount kits and components. We cannot guarantee or confirm fitment when used with products from other manufacturers. Please double-check the required components section to see if anything else is needed for a proper installation. If you are unsure, please contact us.
Before Ordering
〇 Regarding Import Consumption Tax
At the Shafutoya 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), so please confirm compatibility with Japanese domestic vehicles (JDM) before ordering. (If you are unsure if a listed product fits 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, manufacturer, and vehicle model using 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 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 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.
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 plenty of time when ordering. 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 Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not adapted for the "Japanese vehicle inspection system," and we cannot provide strength study reports or similar documentation for Japanese inspections. Therefore, all parts are sold for "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. As 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 replacements for products with shipping damage, defects, or incorrect items if notified within 7 days of receipt. Please also note that for products sold through us, warranty-related support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
