Fits to Primary O/E Catalyst - Pre-PPF models only. (Requires 2 x BMW gasket - part number 18307851168 - not included).

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 M4 (F82) Coupe performance exhaust is made in 3"/76.2mm pipework and fits from the primary catalytic converter section backwards. This exhaust replace the secondary catalyst (Cat Bypass), centre and rear sections.

This exhaust includes the secondary de-cat and 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.

EML lights may activate after removing the standard second O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.

This primary cat back exhaust includes a H-pipe section to combine and equalise the gas flow giving a sportier exhaust note.

Please Note - This performance exhaust retains the use of exhaust valves. When switching drive modes (e.g. Normal to Sport+ mode) your exhaust tone will continue to swop from quieter to louder tones as before.

Requires 2 x BMW gasket - part number 18307851168 - all other relevant gaskets and fittings are supplied.

Press Release

Keen to make a step above and differentiate from the competition, Cobra Sport have used their extensive experience and use of new exhaust technology to create a product which truly stands out in the aftermarket performance market.

The Cobra Sport research and development team quickly made the decision to base the new M4 exhaust systems on 3" (76.2mm) T304 grade stainless steel pipework. The larger diameter 3" pipework enhances the capabilities of the 3.0 litre twin turbo V6 engine and utilising advanced gas flow design, allows for substantial performance improvements. The M4 development has been based around a valved cat back exhaust with the addition of a secondary de-cat (catalyst bypass) exhaust upgrade. The cat back exhaust includes a centre H-Pipe section, designed to mix and perfectly balance gas flow from both sides of the engine to increase power, improve flow efficiency and enhance the exhaust tone.

Extensive road testing was undertaken in order to ensure there was no resonance or exhaust drone in the cabin throughout the rev range in all drive modes. The sound of the new Cobra Sport exhaust boast vastly improved tonal characteristics, with the new exhaust offering a deeper more aggressive sound when under full load. The Cobra Sport exhaust incorporates a pair of exhaust valves designed to utilise the existing valve motors , enabling continued use of the M4 drive modes to adjust the dynamic of the exhaust. In the comfort driving mode the valves remain shut forcing the gas flow through the flow optimised rear box, creating a finely tuned exhaust note for a sporty but unobtrusive sound track for everyday use. With the valves open in Sport and Sport+ mode, the gas flows through all 4 tips creating a highly aggressive sound track.

Cobra Sport Sales Manager Matt Thomas commented, "Building on an existing first class reputation in the BMW tuning market, we're excited to be adding the Cobra Sport sound and performance upgrade to the stunning M4. Power testing the secondary de-cat and cat back system revealed an impressive +21.25bhp and +9.2lb-ft of torque. The free flowing 3” pipework and optimised exhaust technology opens up huge potential for M4 owners looking to increase power whilst also obtaining a pitch perfect exhaust tone."

Cobra Sport have improved the styling of the BMW M4, creating a noticeably enhanced and balanced look to the rear of the M4 with a choice of quad 3.5" (88.9mm) inward rolled baffled or inverted highly polished stainless steel tailpipes. For those looking to take the style upgrade a stage further, upgraded ceramic coated matt black 'Blackout' tailpipes are available.

Quality product but sold on Amazon cheaper with different seller.
Size: Medium Size 2, Color: White-Blue
The size is the reason for the missing star. Made of good quality but found cheaper from another buyer. My 9month Cane Corso hasn't destroyed it yet and enjoys playing keep away with the other dogs.

absolutely must buy perfect for dogs. I have a large black lab and he has had so much fun with us.
Size: Large Size 3, Color: White-Blue
I have to say that my dog would be considered an aggressive tower. However, this ball has stayed intact. I love that it comes with the pump. It’s extremely functional very soft for catching can be cleaned. Very easy easy the quality is exceptional. Very functional does have a bounce. I can say he has had so much fun with this since it’s getting it for his birthday on 11/11 I highly recommend this product and would definitely buy again.

Perfect for keep-away
Size: Large Size 3, Color: Red-Blue
I purchased one of these for my pup and he has a ball throwing it up in the air and chasing it. Handy for something they can play with alone.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.
