What is the Fabspeed Muffler Bypass Exhaust System made from?

The Muffler Bypass Exhaust System is made from 14 to 16 gauge T304L stainless steel, CNC mandrel bent, replacing the factory muffler with free-flowing straight pipes. It includes 200-cell HJS Sport Cats and carries a Fabspeed lifetime warranty.

Does it fit the 996 GT2?

Yes. It is a direct factory muffler replacement for the 2001-2005 996 Porsche 911 GT2 and its 3.6L twin-turbo flat-six. It bolts in place of the factory muffler with no cutting or welding.

How much weight does it save?

The system sheds about 45 pounds, almost all of it from the rear of the car where the factory muffler sits. That weight loss sharpens the car's balance on top of the flow and power gains from the freer exhaust path.

Does it include catalytic converters?

Yes. The system includes 200-cell HJS Sport Cats, which flow up to 93 to 95 percent of a straight pipe and keep the car emissions-scrubbed to help prevent a check-engine light, so the standalone Sport Cats are not needed alongside it.

Yes. By replacing the restrictive factory muffler with straight pipes, it improves flow for stronger power and sharper throttle response than the Factory Equipment. Fabspeed does not publish specific figures for the system alone; the biggest gains come from adding the Sport Headers and a matching tune.

The system includes emissions-scrubbing HJS Sport Cats, but it is not CARB approved, so it is not legal for sale or use in California or other states that require CARB certification. Check your local regulations before installing.

Description

Fabspeed Muffler Bypass Exhaust System for 996 Porsche 911 GT2

Fabspeed’s Muffler Bypass Exhaust System for the 996 Porsche 911 GT2 is the complete rear-exhaust upgrade for the original twin-turbo GT2, replacing the heavy factory muffler with free-flowing straight pipes and shedding roughly 45 pounds from the back of the car. Built by Fabspeed Motorsport, an American engineering house fabricating exhaust systems for the world’s finest sports cars since 1988, it is formed from 14 to 16 gauge CNC mandrel-bent T304L stainless steel and includes 200-cell HJS Sport Cats that flow up to 93 to 95 percent of a straight pipe. The result is stronger flow, sharper throttle response and a deeper, more purposeful voice, with the included Sport Cats keeping the car emissions-scrubbed to prevent a check-engine light, a statement exhaust for one of Porsche’s most uncompromising 911s.

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.
