Does the Fabspeed Valvetronic Supersport X-Pipe fit the McLaren GT and GTS, and which cars need this version?

Yes. The Fabspeed Valvetronic Supersport X-Pipe fits 2020 and newer McLaren GT models and the GTS that followed, both with the 4.0L twin-turbo V8. This is the version for cars that left the factory with valved exhausts, since it keeps those valves working. If your car has no factory exhaust valves, the standard Supersport X-Pipe is the correct choice.

Does it keep the factory drive modes and quiet start?

Yes. The system completely retains the OEM valved exhaust functionality, so every factory drive mode and the quieter valve-closed behavior still work exactly as they did from McLaren. The car's existing controls open and close the exhaust, now through aerospace-quality Helical Limited valves, giving you the louder, more exotic tone on demand and the original civility when you want it.

How much louder and more powerful is it?

With the valves open, expect a higher-pitched, more exotic twin-turbo V8 tone and a modest increase in volume rather than a constant drone. Fabspeed's dyno testing shows gains of around 21 horsepower, and the system also removes about 7 lbs compared to the factory parts, so the car feels sharper as well as sounding better.

Does it require a tune or trigger a check engine light?

No. It is a direct bolt-on that needs no ECU tuning and ships with a no-check-engine-light guarantee, so there are no warning lights or error codes after a correct installation. The factory engine management and valve control stay untouched, which keeps your McLaren GT driving exactly as it did while adding sound, flow, and power.

What are the valves made from, and will they last?

The system uses aerospace-quality Helical Limited exhaust valves imported from the U.K., paired with CNC mandrel-bent T304L stainless steel pipework and a signature investment-cast X junction, all built in-house at Fabspeed Motorsport in the USA. These materials are chosen to handle the heat and pressure of a twin-turbo V8 for the life of the car, backed by the Fabspeed Lifetime Warranty.

Is it hard to install?

No. It is a Level-1, bolt-on installation with no cutting or welding, using factory mounting points mapped from a 3D scan, and it reuses the car's existing valve wiring so there is no separate controller to fit. A step-by-step installation guide is provided, and most owners have a qualified shop complete the fitment in a single visit.

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.
