Does the Fabspeed Supersport X-Pipe Exhaust fit my GT or GTS?

It fits the McLaren GT from 2020 onward and the GTS from 2024 onward with the 4.0L twin-turbo V8. This is the valveless version; if your car came with factory exhaust valves, Fabspeed offers a separate Valvetronic X-pipe, so confirm whether your GT has factory valves before ordering.

What does it do, and how does it sound?

The Supersport X-Pipe Exhaust replaces the OEM muffler with an investment-cast X-pipe that improves flow and scavenging, giving the twin-turbo V8 a smoother, more exotic tone with a slight increase in volume. It also saves 7 lbs, so the car sounds better and loses a little weight without becoming harsh or droning.

Does it need a tune or cause a check engine light?

No. The system is fully plug-and-play: it requires no ECU tune and is guaranteed to cause no check engine light. Because it is designed from 3D scans of the OEM muffler, it bolts straight on and behaves like factory equipment electronically.

What is it made from?

Fabspeed builds it from CNC mandrel-bent T304L stainless steel with a signature investment-cast X-pipe for improved flow and scavenging. It is built entirely in-house in Fort Washington, Pennsylvania, and is backed by Fabspeed's lifetime warranty.

Is installation difficult?

No. It is a simple bolt-on that needs no cutting or welding and installs at Level-1 difficulty using the factory mounting points. A qualified shop can fit it in a single visit, and it reverses cleanly back to the factory muffler if you ever want to return to stock.

Does it affect emissions or the catalytic system?

No. This X-pipe replaces the center muffler only, not the catalytic system, so the emissions hardware stays in place, and it needs no tune and throws no check engine light. The main thing to keep in mind is the small increase in volume for local noise rules.

Does the Fabspeed Supersport X-Pipe fit both the McLaren GT and GTS?

Yes. The Fabspeed Supersport X-Pipe is engineered for 2020 and newer McLaren GT models and the GTS that followed, both built around the 4.0L twin-turbo V8. It is 3D-scanned from the factory center section, so it bolts to the original mounting points without cutting or welding. Confirm your car's exhaust valve configuration before ordering, since valve-equipped cars use a different version.

Does my McLaren GT have factory exhaust valves, and does that change which X-pipe I need?

It can. Some McLaren GT and GTS cars left the factory with valved exhausts and some without, and the two take different hardware. If your car has factory exhaust valves, choose the Fabspeed Valvetronic Supersport X-Pipe, which retains full valve control. If it has no valves, this Supersport X-Pipe is the correct fit. Check with your dealer or VIN if you are unsure.

How much louder and different will my McLaren GT sound?

Expect a higher-pitched, more exotic tone from the twin-turbo V8, with a modest increase in volume rather than a dramatic one. The signature cast X-pipe smooths the pulses from both banks and frees up flow, so the note is cleaner and more purposeful at full throttle while staying comfortable for daily driving. It is a refined upgrade, not a straight-pipe roar.

Does the Supersport X-Pipe require a tune or trigger a check engine light?

No. The system is a direct replacement 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. It works with the factory engine management untouched, which keeps your McLaren GT's drivability exactly as McLaren intended while adding the sound and flow benefits.

Is it a difficult installation?

No. It is a Level-1, bolt-on installation with no cutting or welding, using the factory mounting points mapped from a 3D scan. A step-by-step installation guide is provided, and most owners have a qualified shop complete the fitment in a single visit. Because nothing is cut, the factory center section can be refitted later if ever needed.

What is the Fabspeed Supersport X-Pipe made from, and will it last?

The Fabspeed Supersport X-Pipe is made from CNC mandrel-bent T304L stainless steel with a signature investment-cast X junction, built in-house at Fabspeed Motorsport in the USA. T304L resists heat and corrosion for the life of the car, and the complete system weighs about 7 lbs lighter than the factory parts. Every unit is backed by the Fabspeed Lifetime Warranty.

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.
