Transform the character of your MINI with the Akrapovič Sports Catalyst Downpipe — a precision-engineered upgrade designed for the R55–R61 Cooper S, JCW, and GP models equipped with the N14 or N18 engine. Renowned for their craftsmanship and motorsport heritage, Akrapovič delivers a downpipe that elevates performance, reduces back-pressure, and unlocks a more engaging, resonant exhaust note.

Constructed from premium stainless steel and built with Akrapovič’s signature attention to detail, this sports-cat downpipe offers improved exhaust flow compared with the restrictive factory component. The result is quicker turbo spool, enhanced throttle response, and the potential for measurable gains in both torque and horsepower — especially when paired with appropriate ECU calibration.

High-Flow Sports Catalyst

The integrated high-flow catalytic converter strikes the perfect balance between performance and emissions control. It provides substantially lower restriction while still maintaining MOT-friendly emissions behaviour* and reducing unwanted exhaust odours associated with decat systems. This makes it an ideal choice for fast-road builds and tuned MINIs seeking improved driveability without compromising refinement.

Precision Fitment for N14 & N18 Engines

Designed specifically for all MINI Gen 2 turbo petrol engines — including Cooper S, JCW, GP and GP2 models — the downpipe ensures excellent compatibility with both factory and aftermarket cat-back exhaust systems. The robust construction resists thermal fatigue, a known weakness in OEM components, offering long-term durability even under high-temperature performance use.

Sharper Sound, Not Excessive Noise

Akrapovič’s acoustic engineering delivers a deeper, more purposeful tone without overwhelming cabin noise. The result is a sound profile that matches the MINI’s sporty character while retaining everyday usability.

Whether you're chasing improved road performance, preparing for track use, or upgrading as part of a staged tuning package, the Akrapovič Sports Catalyst Downpipe offers a premium, future-proof foundation for extracting more excitement from your MINI.
