Evolution Racewerks 2012+ BMW N55 335i 435i M135i M235i F2x/F3x Turbo Competition Series Catless Downpipe

Application:

• 2012+ BMW 335i (F30 Chassis) N55 Engines
• 2013+ BMW 435i (F32/F33 Chassis) N55 Engines
• 2012+ BMW M135i (F20/F21 Chassis) N55 Engine
• 2012+ BMW M235i (F22 Chassis) N55 Engine
• The F Series (1,2,3,4 Series) N55 cars all share the same downpipe.  When first introduced, the downpipes had a 3.5" v-band flange intlet on the turbocharger side.  On 07/13, BMW decided to change the downpipe.  This new downpipe featured a 4" v-band flange inlet instead.  Thus, the previous downpipes are not compatible with the new ones. See Below:

• 335i (U.S. Spec) - Up to 07/13 have the old downpipe (BM-EXH007)

  After 07/13 have the new downpipe (BM-EXH012)

• 435i (U.S. Spec) - All 435i have the new downpipe (BM-EXH012)

• M235i (U.S. Spec) - All M235i have the new downpipe (BM-EXH012)

• M135i (European Spec) - Up to 07/13 have the old downpipe (BM-EXH007)

  After 07/13 have the new downpipe (BM-EXH-012)

Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars.  Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly.  The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction.  The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves.  Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction.  It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction).  By replacing the factory downpipe/catalytic converter with our Competition Series 4" Catless Downpipe, more power is unleashed! 

Additional O2 Sensor Bung -  An additional O2 sensor bung can be added so that you can easily add a wideband o2 sensor and gauges so that you can monitor air/fuel ratios.  The additional O2 sensor bung will come pre-installed with a plug so that you do not need to run the o2 sensor right away.

Optional EGT (Exhaust Gas Temperature) Bung - An additional 1/8" NPT bung can be added so that you can easily add a EGT sensor and gauge.  The optional EGT sensor bung will come pre-installed with a plug so that you do not need to run the EGT sensor right away.

Notice of Fault Codes/Check Engine Light - Using any Racing downpipe could result in a check engine light and fault codes, even with sport cats. Although we have heard of cases where no check engine light appeared, these Racing downpipes are not designed to meet emissions testing and regulations. Race software that is specific to your mods is strongly advised to better adapt your car to a racing environment, keep the fault codes from appearing, optimize power gains, and improve general drivability.
