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.

The sports cat option has been designed utilising 3.5"/88.9mm pipework with a 4.5 in/114.3mm 200 cell high flow sports catalyst, maximising the flow rates and optimising the tuning potential of the Mercedes-AMG A 45 S. When equipped with Cobra Sport's 200-cell high flow sports cat (and supporting modifications) and specialist EST Performance stage 2 remap, the Mercedes-AMG A45S produced 499.5BHP (+70BHP). The high-flow sports cat exhaust version will enable you to pass a UK MOT emissions test or police road side checks.

The large bore 3.5"/88.9mm de-cat exhaust version is sold for motorsport and off road use only and will NOT be able to pass a UK MOT emissions test or police road side checks.

Cobra Sport's high-flow downpipe has a selection of fitment options, for those who want a zero compromise approach and a full stainless-steel downpipe, the Cobra Sport flexi section replaces the factory mild steel flex section with a TIG-welded T304 stainless steel flex for maximum strength and longevity.

Both the ‘Including Cobra Sport Flex Upgrade’ and Downpipe ‘To Standard Flex’ options are compatible with both the standard and Cobra Sport cat back systems.

Sports Cat Test Results:

Sound - Engine at Idle: 69dB (+6.7dB) - Static 4,000rpm test: 93.8dB (+13.1dB)

All relevant fittings and gaskets are supplied.

IMPORTANT: This exhaust removes the PPF (Petrol Particulate Filter) and will require engine tuning at time of fitment to cancel the EML light.

Fitment is for motorsport and off-road use only as this system removes the PPF filter.


The product images shown are for illustration purposes only and due to product enhancement may not be an exact representation of the product.

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 accepts no responsibility for the use of parts which remove emissions devices on the public highway. It is the customers responsibility to ensure that all local laws are adhered to within their home state/country.
