Turbo downpipes for BMW F80 M3, F82 and F83 M4
Replace the OEM pre-catalytic converters
(catless downpipes or cat delete)
The Supersprint downpipes are built in Aisi 304 Stainless steel, TIG welded and mandrel bent.
They fit perfectly without any adaptation, with O2 sensor bungs, flanges and mounting brackets all matching the OEM parts.
They are mostly responsible for the performance increase given by the Supersprint exhaust, thanks to the improved flow right after the turbos.
Because the secondary O2 sensors will read the wrong values once these components are fitted, the Check Engine Light will turn on (CEL). This issue must be addressed with O2 sensor cheaters, also known as micro-cats, or with a specific ECU tune. More information available on request.
