We have just installed the SUPERCIRCUIT direct bolt-on Downpipe to the BMW F30 328i (N20 engine) below.
Here is how the turbo outlet looks like on the BMW F30 328i, after the factory stock original downpipe is removed from the N20B20 engine.
The stainless steel SUPERCIRCUIT Catless Downpipe promotes better and less restricted exhaust flow, compared to the factory stock original downpipe which has a huge catalytic converter as shown in the picture below.
The SUPERCIRCUIT Downpipe is made for direct bolt-on application and is compatible with the rest of the factory stock cat-back exhaust system of the BMW F30 328i (N20).
No other mod is required during the installation, just clamp onto the turbo outlet and slot onto the slip-joint of the cat-back exhaust system as shown in the pictures below.
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.
