This downpipe is listed for Mini Cooper S models using the 1.6 R-series engines: Clubman S R55 (2008–2014), Cooper S R56 (2007–2013), Cabrio/Convertible R57 (2009–2015), Coupe/ Roadster R58/R59 (2012–2015), Countryman S R60 (2011–2016) including ALL4, and Paceman S R61 (2013–2016) FWD and ALL4. Verify your exact chassis code (R55–R61) before purchase.
The pipe is made from T304 stainless steel with a 1.5 mm wall thickness. It features TIG welding for strength and longevity, CNC-machined flanges for accurate fitment, an integrated flex section to reduce exhaust strain, and a hand-polished mirror finish.
Both the inlet and outlet diameters are 2.5 inches.
Yes — the downpipe comes with an O2 sensor bung and includes one gasket as shown in the product pictures.
The listing states it is a direct fit bolt-on with no modification required. However, professional installation is highly recommended to ensure correct fitment and sealing.
According to the product description, the downpipe can improve power and torque across the RPM range, improve throttle response, reduce exhaust gas temperature, and produce a deeper exhaust tone. Actual gains depend on vehicle condition, supporting mods, and tuning.
Any change to the exhaust path can affect sensor readings. The downpipe includes an O2 bung to retain the O2 sensor, but if the unit is catless or materially alters catalytic function it may trigger a CEL and could make the car non-compliant with local emissions laws. The listing does not explicitly state whether a catalytic converter is included—confirm with the seller and check local regulations before installation.
The product description does not explicitly state whether a catalytic converter is included. Contact the seller for clarification if you require a catalyzed or high-flow catted version.
The part comes with a 2-year warranty against manufacturing defects. Warranty terms and exclusions (installation damage, misuse, emissions-related issues) should be confirmed with the seller.
The package includes the downpipe and one gasket. No installation instructions are included, and other hardware (bolts/studs) is not guaranteed—bring or reuse OEM hardware or verify with the seller.
Typical installation requires basic mechanic tools, an exhaust jack or lift, penetrating oil for old fasteners, torque wrench, and an O2 sensor socket for the sensor. Due to vehicle uplift and alignment needs, professional installation or a well-equipped shop is recommended.
The T304 stainless steel construction and mirror polishing provide good corrosion resistance and reduced discoloration compared with lower-grade steels. Over time high heat can still cause some tinting; T304 resists but does not eliminate all color change under extreme conditions.
You may or may not require a retune. Some vehicles run fine with only a downpipe (and the factory O2 sensor reinstalled), while others benefit from ECU adjustments to optimize fueling, boost control, and to prevent knock or CELs. For best results and reliability, consult a tuner or professional installer.
The listing advises contacting the seller for any needs. For warranty claims or returns, contact the seller or the marketplace where you purchased the item to confirm return procedures, shipping, and warranty service details before installing the part.
