What does it do to power and weight?

On Fabspeed's dyno the Supercup Race Exhaust adds 22 horsepower and 16 lb-ft of torque, and it strips a dramatic 35 pounds from the rear of the car. The power comes from replacing the restrictive factory muffler with free-flowing 3-inch stainless tubing. On a light car like the 930, the weight loss is felt as sharper handling.

It is loud and aggressive, as the Race name suggests, but the resonated design keeps the sound composed rather than a flat drone. It gives the 930 a hard, race-bred voice with real presence under boost. If you want a quieter setup that keeps a catalyst, Fabspeed's Muffler Bypass with Sport Cat is the milder choice.

What is the difference between the standard and dual-outlet setups?

The standard setup uses the factory single-outlet layout and bolts on with no cutting. The dual-outlet setup routes to two outlets for a more aggressive look, but it requires some modification to the rear bumper valance to fit. Both come with a choice of oval or quad tips, selected at checkout.

It is not CARB approved, so it is not for sale in California or other states that require CARB certification. Emissions rules vary by state, so check your local requirements before buying. It is built as an aggressive performance exhaust rather than an emissions part.

Is it hard to install, and is it covered?

The standard setup is a simple bolt-on that installs on the stock turbo or an upgraded K27 with no cutting or welding; only the dual-outlet configuration needs bumper-valance work. Professional installation is recommended for a proper seal. Every Supercup Race Exhaust is backed by the Fabspeed Lifetime Warranty.

Fabspeed Supercup Race Exhaust System for 930 Porsche 911 Turbo

Fabspeed’s Supercup Race Exhaust System for 930 Porsche 911 Turbo is the loud, aggressive answer for the original air-cooled 911 Turbo, a resonated muffler-bypass exhaust built to shed weight and shout. Fabspeed has built exhausts for Porsche for more than thirty years at its own Fort Washington, Pennsylvania facility, and this system replaces the heavy factory muffler with complete 3-inch, 76.5mm CNC mandrel-bent T304 stainless tubing and a resonated design that keeps the sound aggressive but composed. On Fabspeed’s dyno it adds 22 horsepower and 16 lb-ft of torque and strips a dramatic 35 pounds off the back of the car, and it bolts directly to the stock turbo or an upgraded K27. Offered with a standard or dual-outlet setup and a choice of oval or quad tips, backed by the Fabspeed lifetime warranty, it is the exhaust for a 930 owner who wants their car to sound as serious as it looks.

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.
