Does this Akrapovic exhaust fit the Porsche 911 GT3 RS?

No. This kit is built for the standard 911 GT3 and GT3 Touring (991.2, 2018–2019) using tail pipe TP-T/S/17. The GT3 RS requires a different Akrapovič tail pipe set and isn't covered by this listing. Contact us if you need help identifying the correct exhaust for your GT3 RS.

What's included in this GT3 exhaust diffuser kit?

This kit includes the titanium slip-on muffler section, a matching titanium tail pipe set, and a carbon fiber rear diffuser. It's a complete acoustic and visual upgrade over the stock exhaust, with no additional parts needed for installation on a 991.2 GT3 or GT3 Touring.

Is this exhaust system street legal?

No. This Race Line system is not CARB compliant and does not meet federal emissions requirements for street or highway use. It's intended for track and off-road use only. Ask us about Akrapovič's street-legal Slip-On Line options if you need a compliant setup.

How much weight and power does this exhaust add?

The titanium muffler and tail pipe combination cuts weight by 1.4 kg versus the stock exhaust while adding up to 4.6 kW (6 hp) and 10.4 Nm (8 lb-ft) of torque at 4,200 rpm. The carbon fiber diffuser is purely cosmetic and doesn't affect these figures.

Does the GT3 exhaust diffuser kit require any tuning after installation?

No ECU tuning is required. The muffler bolts directly to the factory mid-pipe at stock mounting points, and the tail pipes and diffuser install using factory-matched hardware. Professional installation is still recommended for proper fitment.

Description

Akrapovic Titanium Slip-On Race Line w/ Tail Pipe Set & Carbon Fiber Diffuser for 991.2 Porsche 911 GT3 & GT3 Touring

The Akrapovic Porsche 911 GT3 Exhaust is a hand-built titanium slip-on race line that brings race-developed Akrapovic engineering to the Porsche 911 GT3. By replacing the heavy factory exhaust it removes roughly 54% of the system weight, sharpening throttle response and improving balance over the rear axle. On the dyno it frees up to 9hp and 11ft-lbs while transforming the car’s voice into the deep, layered Akrapovic tone that builds with revs and stays drone-free at a cruise. This kit bundles the titanium muffler section with a matching titanium tail pipe set and a carbon fiber rear diffuser, giving you a complete exhaust and rear-fascia upgrade in a single purchase — no separately sourced parts required.

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.
