Will the Fabspeed Pre-Muffler Pipe for Porsche 911 fit my 3.0 or 3.2?

Yes. The Pre-Muffler Pipe for Porsche 911 Carrera models covers 3.0L cars from 1976 to 1983 and 3.2L cars from 1984 to 1989. It is a direct replacement for the factory component in the same position, using the factory mounting points, so nothing is cut, welded or fabricated to fit it.

How much power does it add?

Fabspeed publishes 18 horsepower and 21 lb-ft over the factory component, along with 8 pounds saved. The gain comes from a straight-through path that holds gas velocity where the original scrubbed it off, so the practical effect is sharper throttle response across the range rather than a single peak figure.

Can I use it on the street?

Fabspeed sells this pipe for closed-course and off-road use, and the rules vary by state and municipality, so it is worth settling before ordering rather than after. Owners who want a gain without that restriction should look at the Fabspeed Sport Cat for the 3.0 and 3.2, which retains a catalyst core.

Will it throw a check engine light?

It may, and it depends on the car. These are pre-OBD2 cars, so a carburetted or CIS 3.0 has no light to set, while a fuel-injected 3.2 running Motronic may flag it. The pipe includes an integrated O2 sensor bung, so on fuel-injected cars the management keeps reading the exhaust normally.

Does it make the car raspy?

No. The resonator is packed with stainless steel wool, which is what keeps the tone full and throaty rather than thin and sharp. Fabspeed describes the character as a gutsy European pre-muffler sound. The packing is stainless rather than fibre, so it will not burn out and turn harsh over the years.

What else should I look at for a 3.0 or 3.2?

The Maxflo and Supercup exhaust systems address the muffler end of the car, and the RSR Header Muffler Kit replaces headers and muffler together for the largest gain in the range. This pipe sits ahead of all of them, so it pairs with any of them rather than competing.

Description

Fabspeed European Pre-Muffler Pipe for Porsche 911 Carrera 3.0 & 3.2

Fabspeed’s Pre-Muffler Pipe for Porsche 911 Carrera 3.0 and 3.2 models is a replica of the component Porsche fitted to cars built for markets outside the United States, and it is the first restriction worth clearing on an air-cooled 911. A straight-through path with a stainless-packed resonator replaces the heavy factory unit, which is why the flat-six suddenly sounds like the thing it always was underneath. Fabspeed publishes 18 horsepower and 21 lb-ft on this pipe, with 8 pounds off the back of the car. This is a competition component with the usage restrictions that come with one, and for an owner building a 3.0 or 3.2 for track work, it is where the meaningful gains start.

Features

Gains of 18 horsepower and 21 lb-ft over the factory component
8 pounds lighter than the part it replaces, taken off the rear of the car
Straight-through resonator packed with stainless steel wool, so it will not burn out
Gutsy European pre-muffler sound character, fuller rather than sharper
Integrated O2 sensor bung so the fuel injection keeps managing mixture, idle and part throttle
Mandrel-bent T304L stainless steel construction
Replica of the European specification component
Bolt-on installation, no cutting or welding required
Fully reversible, the factory component refits at any time
Backed by the Fabspeed lifetime warranty

Applications

Porsche 911 Carrera 3.0: G-Model | 1976-1983 | 3.0L F6
Porsche 911 Carrera 3.2: G-Model | 1984-1989 | 3.2L F6

Notes

The 3.0L cars in this range are sold in some markets as the 911 SC; Fabspeed lists the fitment as 911 Carrera 3.0 from 1976 to 1983
This is a competition component, sold for closed-course and off-road use, and buyers should check local, state and federal law before ordering
Fitting this pipe may set a check engine light, depending on the car’s year and management system
The integrated O2 sensor bung applies to fuel-injected cars; carburetted and CIS cars without a sensor simply leave it unused
All Fabspeed products are expected to ship within one week of order, and timelines are often much 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.
