Description
Supersprint BMW N55 Catless Downpipe (Replaces catalytic converter)
Supersprint Inc. was formed in 1955 with the objective of designing and building the highest quality exhaust systems in the world. Every Supersprint system has been researched, designed and tested to insure additional power and to enhance overall performance. All design is validated by extensive testing which includes hours of dyno testing on Supersprint's Maha 4-wheel chassis dynamometer. In fact no other exhaust manufacturer, race team engine testing department or car manufacturer has the performance evaluating experience of Supersprint!
Please note: This system replaces the front catalyst and gives more flow in the exhaust system! the system can not pass the MOT! after installing the system you might get error messages in the cockpit because of wrong lambda values! Anyhow this the downpipes brings a lot of power, and are a "must have" if you want to get the most out of your BMW turbo engines! The system is handmade of 100% stainless steel, and has perfect fitment and performance!
The Supersprint catless 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.
Please note:
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. Replace the OEM pre-catalytic converters
