Additional Details

MODEL YEAR:

**BMW made two versions of the factory downpipe for the new F Series N55 Engine.  The early version ran from build date 2012 to 08/2013.  The second version ran from build date 09/2013 and on.  The build date of your car can be found on a stick on the driver's side door jam.  These downpipes are not interchangeable.  Make sure you order the correct downpipe for your car.

CAUTION: This product is intended for OFF ROAD USE ONLY. Not legal for use on pollution controlled vechiles upon public highways.   THIS PRODUCT IS FOR SALE FOR ALL 49 STATES EXCLUDING CALIFORNIA.  THIS ITEM IS NOT FOR SALE, INSTALLATION, OR USE ON LICENSED VEHILES IN THE STATE OF CALIFORNIA. This does not affect any international customers.

 ER's Competition Series Catless Downpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping.  They are 100% TIG welded by their in house fabricators and built in the USA.  The factory turbocharger turbine housing utilizes a V-Band flange which they have duplicated and CNC machined cut out of billet 304 stainless steel.  Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods.  The O2 sensor is positioned at the factory location. Since the outlet of the turbocharger is 3.5" and the factory exhaust system is 3", the factory downpipes reduces size using short transitions from 3.5" before the catalytic convert and 3" afterwards.  Due to space needed for the cataylic converter, the factory downpipes reduce in size using very short transitions.  Since ER's catless downpipes delete the cataylic converter, they have more space.  Thus, ER uses very long transitions.  These longer transitions allow the exhaust gas time to smoothly transition from the larger piping to the smaller.  Also, since ER utilizes a larger 4" pipe right after the turbocharger, turbo backpressure is significantly reduced.  This results in less exhaust turbulence and backpressure which again improves throttle response and increase turbocharger spool times (less turbocharger lag).

OPTIONS

 Ceramic Thermal Coating - The purpose of ceramic coating downpipes is to keep heat from the exhaust gases inside the downpipe from radiating out.  This keeps underhood temperatures lower and less heat absortion by nearby parts/surfaces.  Another added benefit is that by keeping in heat (energy) in the exhaust gases inside the downpipe, exhaust flow velocities stay up, resulting in lower backpressure.  The ceramic coating also adds additonal corrosion resistance.  ER utilizes the best ceramic coating possible.  ER's thermal coating can resist up to 2000F of heat.  It is available in black only (all the other colors cannot withstand heat that high).

 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.
