Following to the installation of the SUPERCIRCUIT Downpipe to the BMW E89 Z4 (28i) N20B20 engine last month; we installed another SUPERCIRCUIT Downpipe to the BMW F10 528i with the similar engine and we found out that the downpipe is not exactly similar even though both the BMWs are sharing the same engine.
The BMW F10 528i factory stock exhaust system shown below.
Below is how the turbo outlet looks like on the N20B20 inline 4-cylinder mill of the BMW F10 328i.
The BMW F10 528i downpipe with a big catalytic converter vs. the oversized SUPERCIRCUIT catless downpipe. The catless downpipe promotes better exhaust flow and causes the turbo to spool faster, hence more horsepower and torque can be created by the engine.
The SUPERCIRCUIT downpipe made for the BMW F10 528i is designed to be able to bolt-on straight away. The high precision CNC machined downpipe flange is fastened to the turbo outlet, and at the other end, clamp to the factory stock catback exhaust system (SEE BELOW). Just direct bolt-on, no cut and weld is required during installation.
