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 M3 (F80) Coupe performance exhaust is made in 3"/76.2mm pipework and fit from the second catalytic converter section backwards (Cat-back) this exhausts replace the centre and rear sections.

This secondary cat back exhaust includes a centre 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.

All relevant fittings and gaskets 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 M3 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 straight-6 engine and utilising advanced gas flow design, allows for substantial performance improvements. The M3 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 M3 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 M3. 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 M3 owners looking to increase power whilst also obtaining a pitch perfect exhaust tone."

Cobra Sport have improved the styling of the BMW M3, creating a noticeably enhanced and balanced look to the rear of the M3 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.

Great Magnesium Blend That Actually Works
Size: 100 Count (Pack of 1), Size: 100 Count (Pack of 1)
I’ve been taking Life Extension Magnesium Caps (500 mg) for a few weeks now, and I can really feel the difference. It’s a blend of magnesium oxide, citrate, and succinate, and I’ve noticed improved sleep quality and fewer muscle cramps at night. The capsules are easy to swallow and don’t upset my stomach, which has been an issue with other magnesium supplements I’ve tried. Plus, I like that they’re vegetarian-friendly and come in a 100-count bottle, which lasts a good while. What I appreciate most is how balanced this formula feels. I take it mainly for sleep, muscle support, and overall well-being, and I genuinely notice I feel more relaxed, especially in the evenings. For the price and quality, it’s a great value. I’ll definitely keep this one in my daily routine.

This Magnesium Is Worth It!
Size: 100 Count (Pack of 1)
Life Extension is a quality company, and this Magnesium is very good. I have been taking it for maybe a year, and it helps me steer clear of debilitating nightly leg cramps, and also helps my digestion from getting sluggish. I don't really see any reason to change brands, because I trust Life Extension to deliver a high-quality product, so I'm just gonna stick with it. Recommended!

Truly a miracle worker!!
Size: 100 Count (Pack of 1)
I used to wake up every day and struggle to go to the bathroom. After taking these for just one week straight, I have already started to become normal having at least one bowel movement a day. This is my third bottle. I take them everyday and don't think I will stop.

Only one capsule per day
Size: 100 Count (Pack of 1)
You need to be careful when comparing vitamins and supplements anywhere you choose to buy them because although they will advertise 500mg,for instance, some you need to take two tablet to get that 500mg. I think that is a little shady and makes it harder to compare. I chose to go with the 1 capsule equals one dose brands. It just makes me trust them more. This is one of those brands. I actually have only been taking them for a week or two but if they were not 500mg and a good quality magnesium my body would tell me in just a few days. These have been working fine for my sleep and nerve pain so i do recommend them. There is only one con I would have yo say that I wish they would specify what percentage of which type of magnesium this is. Most likely the oxide at this price but it just would be nice to know. I have the subscribe and save so plan on sticking with it. Good price and it is what they tell me it us plus only one per day. Nice find.
