BMW B58 Super 5" Decat Downpipe (F Series M140i, M240i, 340i & 440i)

Description

This is the largest BMW B58 downpipe on the market with a smooth transition from 4.5" to 5" to 4" to the OEM connection of 3.3". This makes this downpipe compatible with the OEM exhaust system and most aftermarket exhaust systems available.

Nearly all the downpipes on the market neck down quickly to 3" right the start of the flex joint. The most important section of the exhaust is right after the turbo & why we now have what you see here. If you're looking for the least restrictive decat downpipe available, this is your answer.
