What vehicles does the Fi Exhaust DBX707 system fit?

It's built specifically for the Aston Martin DBX707, model year 2023 and newer, with the 4.0L twin-turbo V8 — a direct bolt-on replacement, no cutting or modification required. It's only compatible with OPF-equipped vehicles.

What is the Fi Exhaust DBX707 system, and how does it work?

It's a valvetronic catback exhaust with individually designed muffler internals. The valves switch between a quieter street mode and a louder race mode, controlled through your vehicle's factory sport button or drive modes, or an optional Fi Pro remote upgrade.

What is the exhaust made from?

T304 stainless steel construction throughout.

Are downpipes available, and will they increase horsepower?

Yes. Race Downpipes are offered in a standard version and a sensor version with a dummy oxygen sensor, and Sport Cats are available as a 200-cell option. Fi Exhaust reports an average horsepower increase of 5 to 10%, along with improved torque, with the complete system fitted in comparison to Factory Equipment.

Can I control the valves remotely?

Yes. Valve operation works through the vehicle's factory sport button or drive mode selector, or can be upgraded to the Fi Exhaust Pro Control System for app-connected remote control.

Do I need to order the whole system at once?

No. Each part of the Fi Exhaust system (catback, downpipes, coatings) is ordered separately, so you can build the configuration you want.

Description

Fi Exhaust Valvetronic Exhaust System for AM8 Aston Martin DBX707 (OPF)

Fi Exhaust DBX707 system is built for an owner who expects the world’s fastest SUV to sound the part. Fi Exhaust has spent years tuning valvetronic systems for Lamborghini, Ferrari, McLaren, and Porsche, and that same commitment to individually voiced muffler internals carries over here: no shared core borrowed from another platform, just a system engineered specifically for the DBX707’s twin-turbo V8. Crafted in premium T304 stainless steel with electronically actuated valves, it resolves the old trade-off between low-end torque and top-end power, staying composed and quiet for daily use, then opening to an intense, race-derived voice that matches the vehicle’s performance. For a vehicle built to outrun expectations, this is the sound that finally catches up.

Valve

Fi Exhaust systems are equipped with valvetronic technology, designed not only to control sound volume but also to enhance overall vehicle performance. Prior to this innovation, achieving both high horsepower and torque presented significant challenges in exhaust system design. Valvetronic technology resolves this conflict, enabling vehicles to deliver robust torque at low RPMs while maintaining impressive horsepower output at higher revs.

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.
