2012-2017 BMW N20 328xi 328i 320i F30 F31 F34 2.0L DOWNPIPE

Circuit Werks latest Satin / Brush Finish 4" turbo downpipe for the BMW F30/F31/F34 N20 motors. There are 13 states that will have SULEV (SUPER ULTRA LOW EMISSIONS VEHICLE) cars. They are California, Arizona, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and the District of Columbia. Thus, 99% of the cars built after March 2012 in those states are N26 engines. While, the remaining states should have N20 engines, there still is a chance you may get the N26 engine.

The same applies for the states that have the SULEV cars. The best way to tell if you have an N20 or N26 is to check your own individual car underneath the factory hood (bonnet), there will be a sticker showing the emissions specs of the car. 

Fits F20/F21/F22/F30/F32F33/F36 with the N20 motors from 2012+ perfectly with stock turbo or an aftermarket turbo using the stock V-Band Clamps. All made out of Stainless Steel and T.I.G. welded.  If you're unsure which downpipe you need for your car, please contact us and I can verify if it fit ours or not.  Please check out our other listing for all the other BMW turbo downpipes.

Professional installation might be required but this is a direct bolt-on.  Comes with three o2 bungs with plugs, if you do decide not to use them.  Might not pass smog in some States even though there are secondary catalytic converters on your exhaust mid pipes.
