Description
SLN Performance - BMW B58 5” Ceramic Coated Decat Downpipe M140i M240i 240i 440i
The SLN 5" Ceramic Coated super decat downpipe is made to fit the legendary Gen 1 BMW B58 (OPF/Gen2 downpipes also available). The bore of this pipe is massive, the 5" tube gradually steps into the 4" flexi pipe, which is the biggest pipe combination available on the market today for the Gen 1 B58. This design ensures maximum, uninterrupted flow and is for those that want the most sound and performance from their B58. The ceramic coating will help keep IAT down, which is a particular problem with the B58 as the downpipe is below the airbox.
This item fits the following BMWs:
2016+ F20/F21 F22/F23 BMW M140i, M240i & M240i xDrive
2016+ F30 BMW 340i
2016+ F32 440i
The use of de-cats, sports cats and removing OPF are for off road/motorsport use only. Using these parts would inhibit your vehicle from passing a MOT test.
Only EC type-approved components are legal and fit for road use.
