Is the Slip-On Line for 991.2 GT3 street legal?

Yes. This system carries EC type approval and is legal for public road use as installed. It's a different product from Akrapovic's Race Line for this chassis, which is explicitly track-only and does not meet street emissions compliance. No ECU remap or tune is required for this street-legal version.

Does this exhaust fit the GT3 RS instead of the base GT3?

No. This specific system is designed for the base 911 GT3 and GT3 Touring, paired with the GT3-specific tailpipe set. The GT3 RS uses a different Akrapovic tailpipe pairing. If you drive a GT3 RS, confirm you're ordering the RS-specific version to ensure proper fitment.

Are tailpipes included with this exhaust?

Yes. This system ships complete with a pair of titanium tailpipes, so there's nothing else to source before installation. It's a fully assembled, ready-to-install slip-on system.

How much weight and power does this system add?

The titanium construction cuts 1.4kg from the exhaust system, a 16.3% reduction versus stock. Akrapovic's own testing shows a gain of 4.6kW (6.2hp) at 4,200rpm along with 10.4Nm of additional torque at the same engine speed, achieved through reduced backpressure and the lightweight titanium construction.

Does installing this exhaust require an ECU remap?

No. This is a street-legal, EC type-approved system that installs without any ECU modification or remap, keeping your GT3's factory calibration intact while delivering a noticeably sharper exhaust note.

What years does this fit?

This system is confirmed for the 2018-2019 991.2 GT3 and GT3 Touring. Some sources suggest fitment may extend into 2020 depending on market and production timing — confirm your exact model year with us if you're unsure before ordering.

Description

Akrapovic Titanium Slip-On Line for 991.2 Porsche 911 GT3

The Akrapovic Porsche 911 GT3 Exhaust is a hand-built titanium slip-on line that brings race-developed Akrapovic engineering to the Porsche 911 GT3. By replacing the heavy factory exhaust it removes roughly 16% of the system weight, sharpening throttle response and improving balance over the rear axle. On the dyno it frees up to 6hp and 8ft-lbs while transforming the car’s voice into the deep, layered Akrapovic tone that builds with revs and stays drone-free at a cruise. Precision-welded and engineered as a direct bolt-on, it is the definitive exhaust upgrade for the 911 GT3.

Features

Sheds about 16% of the factory exhaust weight for sharper response and better balance
EC type-approved for road use — no engine or ECU modification required for installation
Delivers a sharper, more resonant exhaust note true to the GT3’s motorsport character
Gains up to 6hp and 8ft-lbs over the stock system
Genuine Akrapovic titanium construction backed by manufacturer warranty
Hand-welded titanium slip-on line, race-developed and built as a direct bolt-on

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.
