Do these headers include heat exchange boxes for cabin heat?

No. Fabspeed Sport Headers are built without heat exchange boxes, a design borrowed from Porsche Motorsport Germany's race-spec headers. This reduces weight and heat in the engine bay but means the cabin will not receive heat from the exhaust system, so these headers work best for track use or in warmer climates.

How much power do these headers add?

On Fabspeed's dyno testing, the Sport Headers added 12hp and 9ft-lbs of torque over the factory headers, along with a 10lb weight reduction from the rear of the car, which also helps rear-end handling.

Do these headers affect emissions?

No. These headers replace only the factory header section ahead of the catalytic converters. The OEM catalytic converters remain in place and unaffected, so the vehicle's downstream emissions equipment is unchanged from stock.

How do I know whether I need Bischoff or Gillet flanges?

Vehicles built from 1994 through mid-1996 require Bischoff style flanges, while vehicles built from mid-1996 through 1998 require Gillet style flanges. Buyers should check the product gallery images against their own vehicle before ordering to confirm the correct flange style.

Which 993 models do these headers fit?

They fit the 1994-1998 Porsche 911 Carrera and Carrera 4, the 1996-1998 Carrera 4S, and the 1997-1998 Carrera S, all with the 3.6L flat six, as well as the 1995-1996 Carrera RS with the 3.8L flat six.

Is this product covered by a warranty?

Yes. Like all Fabspeed performance products, the Sport Headers are backed by Fabspeed's lifetime warranty against manufacturing defects, covering the header tubes and merge collector regardless of which flange style is ordered.

Description

Fabspeed Sport Headers for 993 Porsche 911 Carrera / 4 / 4S / RS / S

Fabspeed Sport Headers are OEM-style performance headers for the 993 Porsche 911 Carrera that improve throttle response and power across the RPM range. They are a direct bolt-on replacement for the factory Bischoff and Gillet headers found on all 993 Carrera models and include no heat exchange boxes, a design borrowed from Porsche Motorsport Germany’s race-spec headers. Removing the heat exchangers reduces cabin heat and sheds weight from the rear of the car, which improves handling, making these headers best suited to track use or warmer climates where cabin heat isn’t needed.

Power

Dyno-tested gains of 12hp and 9ft-lbs of torque, with a 10lb weight reduction from the rear of the car

Features

OEM-style design fits like the factory headers, so no custom heat shielding fabrication is required for installation
3-into-1 high-velocity merge collector with 1.75″ equal-length header tubes
Constructed from high-quality 14-16ga CNC mandrel-bent T304L stainless steel
Simple bolt-on installation, no cutting or welding required
Does not affect emissions, as the OEM catalytic converters are unaffected
Backed by the Fabspeed lifetime warranty

1994-1998 Porsche 911 Carrera: 993 | 3.6L F6

1997-1998 Porsche 911 Carrera S: 993 | 3.6L F6
1995-1996 Porsche 911 Carrera RS: 993 | 3.8L F6

Notes

These headers do not have heat exchange boxes and will not provide cabin heat; best suited for track use or warmer climates
After the initial heat cycle, tighten all exhaust bolts to the OEM torque specs to ensure a proper header seal
All Fabspeed products are expected to ship within one week of order, though timelines are often quicker

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.
