Does the Akrapovic Slip-On Race Line for Porsche 718 Cayman GTS 4.0 fit OPF/GPF-equipped cars?

Yes. The Akrapovic Slip-On Race Line for Porsche 718 Cayman GTS 4.0 is compatible with OPF/GPF-equipped cars and does not alter the factory particulate filter. The system replaces the muffler section only, so everything ahead of it stays as Porsche fitted it.

Is this exhaust street legal?

No. Akrapovic states the system is designed for racing track use only and does not meet emission compliance requirements for street or highway use. It is compatible with OPF/GPF-equipped cars and removes no emissions hardware, but the sound level alone keeps it outside road approval.

How much power does the Slip-On Race Line add?

Akrapovic's dyno testing shows gains of up to 4.8 kW (6.5hp) at 3,000 rpm and 15.8 Nm (11.8 lb-ft) of torque at 2,900 rpm over the stock system. The bigger change is character rather than output: a rich, harmonic tone at high revs over a deep low-range note, with 6.5 kg taken out of the rear of the car.

Does this exhaust also fit the Boxster GTS 4.0 or Cayman GT4?

Yes. The same part number, S-PO/TI/18/1, covers the Cayman GT4, 718 Spyder, Cayman GTS 4.0 and Boxster GTS 4.0, since they share the same 4.0-liter flat-six. Akrapovic recommends confirming your production date for GT4 and Spyder models due to a bracket change on early cars.

Can I get black titanium tips instead?

Yes. The same muffler is also sold with black titanium tips under SKU S-PO/TI/18/1-TPB, and this listing is the natural titanium version under S-PO/TI/18/1-TP. Muffler, weight saving, power figures and fitment are identical between the two finishes.

Description

Akrapovic Titanium Slip-On Race Line for Porsche 718 Cayman GTS 4.0 and Boxster GTS 4.0 with Titanium Tips

Akrapovic’s Slip-On Race Line for Porsche 718 Cayman GTS 4.0 pairs the titanium construction and in-house foundry work behind Akrapovic’s reputation with a three-muffler race system, two side-mounted and one central, developed for the naturally-aspirated 4.0-liter flat-six shared by the Cayman GTS 4.0 and Boxster GTS 4.0. Every muffler is hand-crafted in titanium, and the titanium tips included with this kit carry Akrapovic’s dynamic relief surface and engraved logotype rather than a plain aftermarket finish. The result is up to 6.5 hp and 11.8 lb-ft more, a rich, harmonic tone at high revs over a deep low-range note, with none of the drone that plagues cheaper full systems. This is a closed-course build for the GTS 4.0 owner who wants the sound of a factory-backed racing exhaust, not a bolt-on that only sounds the part.

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.
