SUPERCIRCUIT has probably the largest collection of turbo downpipes in the country. Here is one that we have installed to the twin-turbo BMW 335i Coupé (E92) N54 engine.
These downpipes are built for the twin-turbo N54B30 straight-6 engine of the BMW E92 335i. They are made of grade 304 mandrel bent stainless steel pipes and are fully TIG/ARgon welded on CNC machined flanges for direct bolt-on application.
The twin turbo outlets of the N54 engine on this BMW E92 335i (SEE BELOW). The downpipes are fasten with clips.
At the other ends of the downpipes, it is compatible with the factory stock catback exhaust system. Just bolt-on straight, no fuss.
Beside the above SUPERCIRCUIT downpipes made for the twin-turbo N54 engine, we also have the downpipe developed for the single-turbo BMW E92 335i (N55) engine.
This catless downpipe is ideal for ecu tuning or remapping.
