Technical Notes:
As car enthusiasts, we understand the importance of vehicles and parts that you can see, feel, experience, and hear. We knew we needed to develop an exhaust system upgrade to make the 11th Gen Honda Civic’s feel and sound like a fun, sporty vehicle.
The PRL Motorsports N1 Exhaust System features a single-exit design and is constructed from 16-gauge (0.065") 3.00" 304 stainless steel, with smooth mandrel-bent transitions for optimal flow. This single-exit design saves weight and cost while simultaneously increasing performance. Each system comes equipped with one resonator and one muffler, both packed with high-quality, high-density packing. Our engineers carefully calculated tube length, bends, component placement, and muffler/resonator specifications to ensure this exhaust sound is as aggressive as it looks, while eliminating the unpleasant drone common in most aftermarket exhaust systems.
Except for the 3-bolt front pipe flange, all connections are slip-fit for adjustability and packaging purposes. For longevity, adjustability, and serviceability, we chose to use muffler clamp/exhaust hangers to support the muffler rather than welding to the hangers. All components are TIG-welded and fully back-purged to withstand exhaust gas temperatures and external elements. Combine this with our 3" Front Pipe Upgrade to maximize exhaust flow and performance. All kits include premium hardware, components, and gaskets for a seamless installation.
Performance and Sound Benefits:
- Aggressive yet composed sound
- Anti-drone
- Reduced backpressure & increased exhaust flow
Kit Includes:
- 3.00" stainless steel, mandrel-bent tubing
- (1) Stainless steel N1-style muffler

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 will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please confirm whether the product can be installed on a Japanese vehicle (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 check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if a product is sorted by selecting the year, manufacturer, and vehicle model using the tabs on our top page, it does not necessarily mean it will fit a Japanese model without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us if you have any questions before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. An estimate for shipping costs is 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 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 yourself enough time when ordering. If you are in a hurry, please contact us to confirm the delivery date in advance. All products are transported via air freight; they are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are generally all designed and manufactured outside of Japan. Please note that they do not conform to "Japanese vehicle inspection standards," and we cannot provide documents such as strength calculation reports for Japanese vehicle inspection purposes. 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
When your product arrives, please check the contents immediately. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. For items with shipping damage, defective products, or products different from what was ordered, we will handle returns, refunds, or exchanges only if you contact us within 7 days of receipt. Please understand this. Furthermore, for products sold through us, warranty-related support will be handled "only through us." Please note that we do not handle support through other companies or agencies located within Japan.
