Boost Logic Downpipes for Bentley Flying Spur V8

Boost Logic’s Downpipes for Bentley Flying Spur V8 are built for the 2021 and later Flying Spur with the 4.0-liter twin-turbo V8, using TIG-welded fabrication and OEM-like fitment so the install stays straightforward. Boost Logic engineers every section to reduce restriction and improve efficiency from the turbos back, and it names faster spool, stronger midrange and a deeper note as the result. For a four-door Bentley the appeal is character rather than lap times: the downpipes give the V8 more voice while Boost Logic says drivability stays at the level expected of a high-end car.

TIG-welded construction rated by Boost Logic for high-horsepower use
Improved flow efficiency from the turbochargers back

Frequently Asked Questions

Do the Boost Logic Downpipes for Bentley Flying Spur fit the W12 model? No. Boost Logic lists these downpipes for the Flying Spur V8 from the 2021 model year, which uses the 4.0 liter twin-turbo V8. The W12 Flying Spur uses a different engine and is not listed, so these Downpipes for Bentley Flying Spur V8 cars should only be ordered for the V8 model.
Do they fit a 2025 or later Flying Spur? Boost Logic does not give an end year for fitment, and Bentley revised the Flying Spur range for 2025. Because the vendor has not confirmed the later cars, owners of a 2025 or newer Flying Spur should ask Bulletproof Automotive to check fitment with Boost Logic before ordering.
Will the Flying Spur still be comfortable on a long drive? Boost Logic says the downpipes add a deeper, more aggressive tone while keeping the drivability expected of a high-end performance car. The factory rear section still controls much of the cabin sound, so a Flying Spur that keeps it should stay relaxed on long trips, although the V8 will be more noticeable under load.
What does the installation involve? Boost Logic designs the downpipes as a direct bolt-on with OEM-like fitment and describes the install as straightforward, with no cutting or welding. The turbochargers on this V8 sit inside the V of the engine, so the work reaches deep into the engine bay and under the car, and a shop that knows the 4.0 liter engine should do it.
Can I add bigger turbos later? Yes, as far as the downpipes go. Boost Logic states they are compatible with stock or upgraded turbo setups and built for high-horsepower applications. Any turbo upgrade on a Flying Spur also needs the right fuel, cooling and calibration, so plan the full package with Bulletproof Automotive before buying parts.

About Boost Logic

Boost Logic was founded in Austin, Texas in 2003 and made its name with Toyota Supra turbo kits, setting street car records at 6speed record days and the Texas Mile that stood long after the company stopped racing Supras competitively. It designs turbo systems, titanium exhausts, intercoolers and engine components for the Toyota Supra, Porsche 911 Turbo, Nissan GT-R, Ferrari and Lamborghini, and its R35 GT-R builds have trapped over 180 mph in the quarter mile and over 200 mph in the half mile.
