SUPERCIRCUIT has probably the largest collection of turbo downpipes in the country. Here is one installed to the BMW E92 335i with N55 single twin-scroll turbo.
The BMW 335i E92 shown below with N55B30M0 straight-6 engine comes with the single twin scroll turbo.

The BMW E92 335i N55 single turbo downpipe vs. the catless SUPERCIRCUIT Downpipe.
The SUPERCIRCUIT downpipe is made with grade 304 stainless steel mandrel bent pipes and is fully TIG/Argon welded on CNC machined stainless steel flanges of the same material grade to ensure perfect fit and long lasting performance.
The SUPERCIRCUIT Catless downpipe developed for the BMW E92 335i N55 single twin-scroll turbo is compatible with the rest of the factory stock exhaust system. It is just straight bolt-on (SEE BELOW).
This catless downpipe is ideal for ecu tuning or remapping but can also be installed alone without any further tuning if you need more horsepower but do not go too extreme. The later needs an 'O2 sensor defouler' or a 'Mini Cat' to cure the P0420 CEL due to removal of the original catalytic converter.
