MTC Motorsport BMW M140i M240i 340i 440i 540i and 740i 4.5” stainless steel decat downpipe for B58 engine only
This downpipe will fit the following models with a B58 engine:
This will NOT fit the 2018 onwards models with the PPF filter unless it has been coded out and can be removed.
We have tested this product and found increases of around 20-25bhp.
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.
Please note, you will need to swap the gasket in the turbo end of the downpipe over or you will get a smell of fuel in the cabin.
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.
If you would like this product fitted to your car in our Lancashire workshop please give us a call and we can arrange this and also do an exchange with your original cat which usually covers the cost of the downpipe and fitting from us.
This product comes with a lifetime warranty.
