Mini (Mk2) Cooper S / JCW (R58/R59) Front Pipe Sports Cat / De-Cat Performance Exhaust

Upgrade the turbo outlet on your Mini Coupe / Roadster for stronger flow, sharper response and a richer soundtrack

Unlock your Mini’s potential with a Cobra Sport front section designed for the R58 Coupe and R59 Roadster in Cooper S and John Cooper Works trim. This turbo downpipe replaces the factory converter and connects from the turbocharger outlet to the centre section, using 2.5 inch (63.5 mm) pipework to reduce restriction and let your engine breathe.

Choose the setup that suits your build:

• High-flow sports catalyst: improved gas flow and a deeper tone while retaining a catalyst
• Catless race pipe: maximum flow and aggressive sound for track and off-road use

Why enthusiasts pick this Mini R58/R59 downpipe

• Noticeably crisper throttle response and faster spool thanks to freer-flowing 63.5 mm tubing
• Enhanced exhaust note with a purposeful, sporty tone
• Precision-built Cobra Sport quality with a fully guaranteed product for peace of mind
• Direct-fit design from turbo to mid-section, replacing the OE catalytic converter
• All required fittings and gaskets included, excluding the turbo gasket

We’ve fitted this upgrade on customer cars at MJ Modifications and the feedback is consistently excellent: stronger pull through the revs, a deeper soundtrack and top-tier build quality that looks as good as it performs.
