Catless turbo downpipe ( decat pipe ) for BMW Z4 E89 with N20 2.0T engine

This is the main factor in the performance increase of the Supersprint exhaust system.

CAUTION: will trigger the Check Engine Light due to an error relative to the 2nd O2 sensor.
The solution is either a specific sensor cheater (also known as emulator, microcat or spacer) or a custom ECU tune.

May also cause a different error in the ECU caused by the turbo boost getting out of range (too high).
This issue can be addressed through an ECU tune or with a Piggyback module
(which must be coupled with the sensor cheater, see above).

Built completely in AISI 304 Stainless Steel, it replaces the restrictive OEM ceramic cat
with an optimized pipe with Flex-joint, allowing improved flow, better performance and a temperature reduction in the engine bay
This part is the main factor in the performance increase of the Supersprint exhaust system.
It's fitted with the necessary O2 sensor bungs.
