Will the Fabspeed Titanium Rennsport Muffler fit my GT3 or GT3 RS?

It covers the Porsche 911 GT3 and GT3 RS across the 997 and 991 generations, from 2006 through 2019. The muffler is generation-specific, so select the variant matching your exact car and model year at checkout rather than assuming one part covers the range.

Why replace a muffler that has not failed yet?

Because factory GT3 mufflers crack, and the titanium units on RS models particularly so. This is a known problem rather than an occasional one. Fabspeed built this replacement specifically against that failure and covers it with a lifetime warranty, so most owners are buying a solution to a problem they were going to meet eventually.

What is the difference between this and the stainless Rennsport Muffler?

Material. This is titanium; the stainless version is sold separately for each generation at a lower price. Titanium buys weight and a harder, higher tone. If the weight saving is not what you are after, the stainless version does the same job of replacing the failure-prone factory part.

How much weight does it save?

Thirteen pounds, from the rear of the car. On a 911 that is the most valuable place to remove mass, because weight behind the rear axle is what works hardest against the car turning in.

How much power does it add?

Fabspeed quotes 18 horsepower and 27 ft-lbs. On a naturally aspirated flat-six those come from removing restriction rather than adding anything, which is why they arrive across the rev range rather than at a single peak.

Which tip finish should I choose?

Five are offered: carbon fiber, satin black, polished stainless, brushed stainless turn down and titanium. The turn down aims the outlet toward the ground and is the choice for circuits with sound limits. The rest are appearance decisions with no effect on fitment or performance.

Description

Fabspeed Titanium Rennsport Muffler for 997 / 991 Porsche 911 GT3 & GT3 RS

The Fabspeed Titanium Rennsport Muffler exists because Porsche’s own GT3 mufflers crack. It is not a subtlety of these cars, it is a known failure, and the titanium units fitted to RS models are the worst of them. Fabspeed’s answer is a titanium replacement engineered against that failure and backed by a lifetime warranty, which turns a part you were eventually going to buy anyway into a part that also makes the car better. Thirteen pounds come off, eighteen horsepower and twenty-seven ft-lbs go on, and the flat-six picks up the CUP car voice that the factory muffler spends its life containing. One product covers the GT3 and GT3 RS from 997 through 991; you choose your car and your tip finish at checkout.

Construction

Titanium is the right material for this part and the wrong material for the factory version, which is the whole story in one sentence. What matters is not the metal itself but how it is used, and the Fabspeed Titanium Rennsport Muffler was designed specifically around the stress that causes the original to fail. It carries the Fabspeed lifetime warranty, which on a component bought to replace something that cracked is worth more than any specification on the page. Five tip finishes are offered, from matte carbon fiber through to titanium.

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.
