2025 MINI Cooper JCW Is Hiding an Extra Exhaust Pipe

[DimON]

When the new (F66) 2025 MINI Cooper JCW debuted earlier this year, it surprised MINI enthusiasts by shifting from a dual exhaust layout to what appeared to be a single, large outlet. However, that was only part of the story—something had been hiding in plain sight all along.

The single-pipe layout aligns with MINI’s new minimalist design language and reflects the brand’s focus on greater efficiency. It also mirrors JCW race cars, bringing the production model closer to what we’ve seen at the Nürburgring and other tracks around the world. But there’s more beneath the surface.

Upon closer inspection of the images, you can clearly spot a second exhaust pipe just to the left of the center outlet. This design closely resembles the standard MINI Cooper S exhaust, where the second pipe is discreetly tucked behind the rear valance.

Why the 2025 MINI Cooper JCW Has a Hidden Second Exhaust

According to our sources, the second exhaust was an engineering necessity. It’s important to remember that the new F66 JCW carries over its engine—and full drivetrain—from the previous F56 model, including the exhaust system. Since MINI didn’t re-engineer the system, two exhaust outlets were still required to ensure the proper level of back pressure.

Simply put, this was the solution engineers devised to allow MINI’s designers to create the appearance of a single, large central exhaust. From what we understand, performance remains unchanged, and the exhaust functions identically to the system found in the previous F56 MINI Cooper JCW.

The previous F56 Cooper S Exhaust design shows that the “dual exhaust” is nothing more than two small pipes from a single exhaust.

If you look at the schematics of the F56 JCW exhaust, the layout is conceptually similar, with two outlet pipes extending toward the rear. The F66 JCW retains this setup but relocates one of the pipes to the left side of the muffler, concealing it.

What do you think? Should MINI have pursued this direction, matching its race cars and simplifying the design? Or do you prefer the classic dual-pipe look? Let us know in the comments below.
