BMW B58 4.5" Decat Downpipe (F20 F21 F22 F30 F31 F32 F33 F34 F36) (M140i M240i 340i 440i)
This downpipe was engineered with the goal of achieving maximum flow without the excessive price tag. The removal of the restriction from the stock downpipe allows for more power with increased safety. Our decat downpipe reduces turbo lag, exhaust gas temperatures, exhaust backpressure and increases power (20-30bhp gain without tuning). This is all achieved whilst providing a superior exhaust note even when using the stock exhaust downstream.
Diameter: 4.5”
Material: T304 high-grade stainless steel
Installation: Direct fit - 1 to 2 hours (professional installation recommended as it may be a tight fit and require trimming of brackets in some models).
Note: This product may cause engine management light to come on, it is recommended to use a lambda spacer or tune.
This product can be installed at our workshop along with a tune, if required.
