This downpipe will fit all N55 engines that were manufactures before July 2013 which is pre-EWG. This will not fit the M135i from July 2013 and onwards. Please ask if you are unsure.

The BMW 135i downpipe is machined from T304 high-grade stainless steel and are tig welded in house

The decat is fabricated in the UK and the flanges are laser cut between 10-12mm

Sharper throttle response due to faster spool of the turbo

Noticeable power gains and a much more aggressive exhaust note which sounds truly amazing

It produces lower temperatures and less exhaust backpressure due to the relief of the turbocharger. Also, the cylinder charge is increased

There is also a substantial weight saving in comparison to the factory catalytic converter

Mandrel-bent for better gas flow and maximum internal size to ensure ultimate performance without the loss of mid-range torque.

This decat will fit the following models:

We have tested this product and found increases of 10-15bhp.

Professional installation is recommended as some exhausts sit slightly different from others and can be tight although the feedback we have received from this product is that it is very easy to fit.

We also recommend purchasing a Lambda Sensor Spacer(s) to prevent the engine light coming on in most cases. If you search our other items you will find these.
