The BMW F10 520i comes with the N20B20 engine which is similar to the one on the BMW F30 320i, but the downpipe is not exactly similar.
Here is how we installed the SUPERCIRCUIT downpipe to the BMW F10 520i.
The turbo outlet of the N20B20 mill on the BMW F10 520i (BELOW).
The BMW F10 520i factory stock downpipe vs. the SUPERCIRCUIT catless downpipe. The SUPERCIRCUIT catless downpipe has larger pipe size to promote better exhaust flow with less restriction, hence faster turbo spool and higher engine output.
The SUPERCIRCUIT BMW F10 520i downpipe is made with grade 304 stainless steel mandrel bent pipe and TIG/Argon welded on high precision CNC machined flange to ensure perfect fit and compatible with the rest of the stock original exhaust system. (SEE BELOW PICTURES)
The SUPERCIRCUIT downpipe made for the BMW F10 520i is designed to straight bolt-on to the factory stock turbo outlet and is 100% compatible to the stock exhaust system without having any further modification to install.
