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.

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.

BMW 335i (E92) Twin Turbo Downpipe + Catback Custom

Full stainless steel BMW 335i Coupe E92 exhaust system from twin turbo downpipe all the way to the rear muffler system customized by SuperCircuit Exhaust Pro Shop.

The standard BMW 335i Coupe with twin turbo N54 engine is producing 302bhp and 400Nm of torque as claimed by BMW. With such engine output, she definitely needs a good and efficient exhaust system.

First, the twin parallel running exhaust system made of grade 304 stainless steel CNC mandrel bent 2.5" piping from the front to the back is crafted by hand. 

Then, not to be missed out, the 2.5" catless downpipe. By eliminating the restrictive catalytic converters in the factory downpipes, backpressure is reduced significantly which results in faster spool, an increase in power & a more aggressive exhaust note. This 2.5" catless downpipe suits 2007-2010 135i, 335i & 335is, just bolt-on, no further modificaiton is required for installation; but further tuning is required should there be a CEL due to removal of the stock catalytic converter.
