Circuit Werks latest Satin / Brush Finish for the BMW 135i 135is N55 2011-2013 Turbo 4" Downpipe. The difference being this does not come with brackets welded like how the 335 model comes, which has been known to cause fitment issues. Fits E82 N55B30 motors from 2011-2013 perfectly with stock turbo or an aftermarket turbo using the stock V-Band Clamps. Fits all the 135i, 135is, Coupes and Convertibles as long as it's the single turbo N55 motor.  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 in our ebay store.  If you have the 2011+ 135i we also have a similar design downpipe made specifically for the 1 series.

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 tho there are secondary catalytic converters on your exhaust mid pipes.  Typical gain with a tune is around 20+ hp.  We also sell CEL Fixes separately.
