SOUL Performance Sport Downpipe for 982 Porsche 718 Boxster & Cayman

The SOUL Performance 982 sport downpipe wakes up the turbocharged flat-four with more power, quicker response, and a far more engaging soundtrack, all while retaining emissions hardware and avoiding check engine lights. Designed as a direct bolt-on for all North American 2017+ 718 Boxster and Cayman models, this high-flow HJS HD 200-cell catalyst downpipe replaces the restrictive factory unit with thick-wall, mandrel-bent T304L stainless tubing that tapers from 90mm at the turbo outlet to dual 55mm exits, reducing back pressure and sharpening throttle response. Independent dyno testing has shown repeatable peak gains of 14whp and 24ft-lbs of torque, with a notable midrange punch. The result is a deeper, more urgent exhaust note with extra turbo spool and crackle, but without harshness, fumes, or unwanted CELs. Each downpipe is back-purged TIG welded, rigorously quality-checked, fixture-tested for precise fitment, and foam-packed with new hardware and detailed instructions, all backed by the SOUL Performance Lifetime Warranty (with a 3-year warranty on the HJS catalyst) for confident use on both street and track.

Development and Testing

In factory configuration, the 718 tends to be relatively quiet. Replacing the restrictive stock catalyst with a high-flow alternative significantly enhances both drivability and the turbo character, without introducing any unfavorable elements to the overall exhaust tone. The HJS HD 200-cell catalyst, paired with smooth mandrel-bent piping ranging from 90mm to dual 55mm outlets, promotes improved throttle response and a more exhilarating exhaust note. This bolt-on solution requires no modifications and is fully reversible, making it an excellent choice to make the Boxster or Cayman a more thrilling drive.

HJS Catalysts

The catalysts used are of the utmost quality, renowned for industry-leading flow characteristics and exceptional durability. They meet strict EURO 4 emission standards while facilitating an increase in flow, all without triggering a check engine light. The HD design incorporates premium triple foil winding for maximum strength and resilience, and a brazing feature prevents the core from shifting or sustaining damage under sustained high horsepower abuse. The 200-cell design features a premium wash coat of precious metals, ensuring a high level of catalytic effectiveness even with the increased exhaust flow.

Construction

Each downpipe is assembled from mandrel-bent, thick-wall T304L stainless steel, then rigorously quality-checked. Back-purged TIG welding ensures optimal weld penetration and long-term durability.

Bolt-On and Go

Every downpipe is rigorously quality-checked and tested in a fixture to ensure perfect fitment, then foam-packed to arrive in perfect condition. New hardware for the two bolt flanges is included, and thorough installation instructions make it a straightforward task most DIY enthusiasts can complete.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
