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 M135i performance exhaust is made in 3"/76.2mm pipework and fits from the turbo to the centre exhaust to replace the standard catalyst.

This de-cat sports exhaust option 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. This exhaust however, is also available as a high flow sports catalyst version, which will pass these checks.

All relevant fittings and gaskets are supplied.


All Cobra Sport downpipe are manufactured in the UK from certified grade 304 stainless steel and TIG welded for a superior quality finish, with 200 cpsi catalysts.


We also highly recommend to replace the downpipe to turbo gasket when installing the catless downpipe.


With the Cobra Sport de-cat fitted, independent testing revealed an increase of 20bhp at the wheels and 28 lb-ft of torque before a re-map was applied.

  • Made from hand crafted, TIG welded 304 grade stainless steel.
  • CNC SS304 Stainless Steel Flanges.
  • Gains from 20-25hp with tune.
  • Cobra Lifetime Warranty
