Supersprint BMW F20 1 Series, F21 1 Series, F22 2 Series, F23 2 Series & more Stainless Steel Downpipe Kit(Replaces Catalytic Converter)

The Supersprint Downpipe Kit(Replaces Catalytic Converter) is a precision, direct-fit stainless steel upgrade engineered for the BMW F20 1 Series, F21 1 Series, F22 2 Series, F23 2 Series & more. It replaces the restrictive factory component to free up exhaust flow, sharpen throttle response and give your BMW a deeper, more purposeful note.

Supersprint has been handcrafting performance exhausts in Mantova, Italy since 1955. Every system is designed and validated on the dyno – not by assumption – using thin-wall stainless steel and carefully sized tubing that raises exhaust gas velocity while protecting mid-range torque, so you gain real, usable power across the rev range.

• Handmade in Italy from corrosion-resistant stainless steel
• Dyno-developed for genuine mid-range and top-end power gains
• Direct bolt-on fit to the OEM mounting points
• For racing / track use only
• Threaded bung for the oxygen sensor provided
