We have supplied and installed yet another set of SUPERCIRCUIT downpipe to the second generation BMW E89 Z4.
This BMW E89 Z4 is equipped with the sDrive20i N20B20 engine and we have developed the downpipe for it.
The SUPERCIRCUIT BMW E89 Z4 Catless Downpipe is made of grade 304 stainless steel mandrel bent pipes and is fully TIG/Argon welded on CNC machined stainless steel flanges for direct bolt-on application as shown in the pictures below.
At the front, the CNC machined flange of the SUPERCIRCUIT Downpipe fits perfectly to the turbo outlet of the BMW E89 Z4's N20B20 engine.
At the rear of the SUPERCIRCUIT downpipe, it is connected to the BMW E89 Z4's factory stock original cat-back exhaust system via the slot-joint and secured with the original exhaust clamp.
The SUPERCIRCUIT Catless Downpipe made for the BMW E89 Z4 sDrive20i (N20B20 engine) is fully compatible with the factory original cat-back exhaust system as shown in the picture below, no mod or cut is required during the installation.
The catless downpipe is ideal for ecu remapping and tuning needs, it allows the exhaust gas to flow freely and less restrictive, hence faster turbo spooling and lesser turbo lag.
