There are two types of BMW F10 535i downpipe, namely the bellow-type and the flexi-type, differentiated by the type of 'vibration isolation' method used, despite having the same N55B30 engine.
SUPERCIRCUIT has developed the direct bolt-on catless downpipe for both the types of BMW F10 535i (N55).
Here, BMW F10 535i with the 'bellow' type of downpipe has swapped to the SUPERCIRCUIT Catless one:
The factory stock original downpipe of the BMW F10 535i which has a tubular 'bellow' and a huge catalytic converter VS. the SUPERCIRCUIT Catless Downpipe which is fully made from grade 304 stainless steel.
The below picture shows how the turbo outlet of the BMW F10 535i looks like after the factory stock original downpipe is removed.
The SUPERCIRCUIT downpipe is designed for direct clamp onto the turbo outlet of the BMW N55B30 engine and secured via the factory supplied exhaust clamp (see below pictures).
At the other end of the SUPERCIRCUIT downpipe, it is connected to the rest of the BMW F10 535i factory stock catback exhaust system via a slip-joint as shown in the pictures below. So the installation is simply direct plug 'n play, no further mod is required.
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.
