Cobra Sport - BMW 340i Downpipe Sports Cat / De-Cat Performance Exhaust
Tax excluded. Shipping calculated at checkout
Cobra Sport systems are hand crafted in the UK. Usual lead time is 7–10 working days; contact us if you need the latest confirmed manufacturing date before ordering.
Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality.
This BMW M340i performance exhaust is made in 3.5"/88.9mm pipework and fits from the turbo to the centre exhaust to replace the standard catalyst.
The de-cat exhaust version is sold for motorsport and off road use only worldwide.
The sports catalyst version replaces a factory emissions device and is not EC homologated. This may not meet current emission laws for road use in your territory.
All relevant fittings and gaskets are supplied
EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.
Cobra Sport Exhausts are expertly manufactured to order, ensuring outstanding quality and precision. This dedication to high standards means a lead time of 12–15 working days, reflecting the care and craftsmanship that goes into every exhaust system.Product specifications
