Description

SOUL Performance Sport Catalysts for 996 Porsche 911 Carrera / 4 / 4S / S

SOUL Performance Products’ Sport Catalytic Converters for the Porsche 996 Carrera replace the restrictive factory cats with high-flow HJS 200-cell units and a split-bank design that frees up power while giving the 3.4L flat-six a deeper, more aggressive voice. Instead of an X-pipe that can hollow out the tone, SOUL keeps the banks separated to add volume and character, delivering a fuller, almost air-cooled-inspired note with a hint of rasp, all while greatly reducing the chance of a check engine light when used as intended. Built in-house at SOUL’s Willow Grove, PA facility from thick-wall.065″ T304L stainless with smooth mandrel bends and heavy-duty flanges, each set is fixture-checked for precise fitment, supplied with new hardware, and comes in about 2 lb lighter than the factory components(15lb vs 13lb). Designed as a direct bolt-on for all 1999-2004 996 Carreras, these sport cats strike a sweet spot between flow, sound, and reliability, backed by SOUL’s renowned Lifetime Warranty on the piping and a 3-year warranty on the HJS cores for confident use on both street and track.

Development

The factory 996 Carrera catalytic converters are quite restrictive, and upgrading them is a common modification. They took a fresh look at the exhaust design to try and create the best possible solution. Side-by-side sound comparisons with our split bank design and an X-pipe design revealed that an X-pipe lowers yields a hollower exhaust tone and cuts out desirable deeper frequencies on the 996, the difference is very noticeable. Separating the banks adds more volume and character, a more profound and fuller flat-six sound with a hint of rasp, almost air-cooled inspired exhaust note.

Construction

Each set is assembled out of thick-wall 0.065″ T304L stainless steel and rigorously quality-checked in-house. Smooth mandrel bends and thick flanges ensure product longevity. Each set of catalytic converter pipes is tested in a fixture to ensure perfect fitment and then foam packed to ensure they arrive in perfect condition. New hardware is included for the cats to header flanges.

HJS 200-Cell Catalysts

SOUL uses the highest quality catalytic converters, known for their industry, leading flow and durability. They are efficient enough to meet strict EURO 3 emission standards while still allowing for an increase in flow while significantly reducing the changes of getting a check engine light. The HJS HF design uses premium double-foil winding for exceptional strength and durability.

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.
