BMW Mini Cooper R55 R56 R57 R58 R59 R60 Stainless Steel Downpipe

BMW Mini Cooper R55 R56 R57 R58 R59 R60 Stainless Steel Downpipe
Details:
This catless turbo downpipe is designed for the Mini 1.6T turbocharged engine (N14 / N18), fitting Cooper S (R56/R57/R58/R59), Clubman S (R55), Countryman S (R60), and JCW high-performance variants. Constructed from 201 stainless steel with 2.5" (approx. 63.5mm) large-diameter piping and a catless design, it significantly reduces exhaust backpressure, delivering quicker turbo spool and noticeable mid-to-high range horsepower gains. The 1.5mm wall thickness and approx. 11mm thick flanges (ground down from 12mm) ensure durability. The mirror-polished finish provides both aesthetic appeal and corrosion resistance. A direct bolt-on replacement – the ideal first step for any Mini 1.6T performance build.
