Description

Circuit Werks latest Satin / Brush Finish for the BMW F22/F23/F32/F33/F36 M235i/435i/435i X Drive N55 2013+ Turbo 4" Downpipe.  Fits all N55 single turbo motors from 2013+. The factory catalytic converter found in the factory downpipe is a major exhaust flow restriction, especially in turbo cars. By replacing the factory downpipe with the catalytic converter with our 4" catless downpipe, more power will be unleashed. You can definitely feel the difference in power! 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. 

Professional installation might be required but this is a direct bolt-on. Will not pass smog in most states. Comes with two o2 bungs with plugs, if you do decide not to use them. Typical gain with a tune is around 20+ hp.

The most restrictive part of any exhaust system is the catalytic converter.  The stock catalytic converter is meant to filter the flow of the exhaust gases to reduce the amount of harmful gases into the atmosphere.  That is a potential performance restrain.  Downpipe eliminate the stock catalytic converters and reduce exhaust back pressure by maximizing exhaust flow.  This downpipe allows the turbo to spool up a lot faster and also build boost quicker.  The result brings out the vehicle's performance potential by giving it a high free flow exhaust system.
