Dinan Valved Axle-Back Exhaust System with Polished Tips for Mini Cooper Clubman / Countryman (S ALL4) 2017-2024

The Dinan F60/F54 MINI S ALL4 Free Flow Exhaust System is designed to enhance the sporty nature of the MINI Countryman while preserving its utilitarian capabilities. Although the Countryman is often overshadowed by the smaller and more nimble Cooper S hatchback, Dinan's system provides a performance upgrade that MINI enthusiasts have long sought for this model. It offers a significant improvement in exhaust tone, power output, and overall performance while maintaining the versatile, practical nature of the F60/F54.

To deliver a more powerful and refined sound, the exhaust tubing is enlarged to 70mm (compared to the stock 65mm), promoting freer exhaust flow and reducing backpressure. The larger diameter leads to a Dinan muffler equipped with absorption technologies, resulting in enhanced power and a sportier exhaust note complete with the signature MINI exhaust pops. Unlike the stock system, which depends on driving modes for sound control, Dinan's exhaust introduces an electronically controlled valve that can be manually adjusted with a key fob. This feature allows you to switch between a quiet, refined tone for everyday driving and a more aggressive, free-flowing sound with the valve open, transforming the system into a straight pipe for maximum auditory pleasure.

Despite this, the system is carefully engineered to prevent excessive cabin drone at low RPMs, ensuring a comfortable driving experience even when the valve is open. Dinan has struck a perfect balance between practicality and performance, allowing the F60/F54 to be both a capable, everyday vehicle and a sporty, spirited performer.

In terms of craftsmanship, the exhaust is constructed entirely from T304 stainless steel, TIG welded for precision and durability, and finished with a brushed surface for a clean, high-quality appearance. The dual 4-inch (102mm) clamp-on polished tips are double-walled and laser-engraved with the Dinan logo. These straight-cut tips, a signature of Dinan's styling, fill the factory exhaust cutouts perfectly, adding an aggressive yet refined look that complements the vehicle’s sporty character.
