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 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.

Fits to pre-PPF vehicles only.

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 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 3.5in (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.

IMMEDIATE REACTION, PLUS FOLLOW UP AFTER A WEEK!
Style: For Him
**Package arrived LITERALLY 5 minutes ago, here is my immediate initial reaction, and then I'll actually post this after USING the soap and getting a better feel for the product.** Keeping in mind that smell is subjective, here are my knee jerk thoughts on the bars of soap: - Firstly, I can smell the soap through the bag (and box). Whatever scent this is, it's POTENT. - Opening the box, the bars of soap look a LITTLE small. Not egregiously so, but a little bit smaller than your average bar of soap; BUT I check them against a new bar of Dove soap that I have, and they are identical. The eyes are playing tricks on you with these. - Here is the breakdown of the 6 scents - Activated Charcoal. This is what I was HOPING would smell like the "Pine Tar" that other companies (like Dr. Squatch, which I've never used, btw) have, but it is the "soap-est" smelling soap, with a hint of tar. It smells a little bit like a can of new paint. - Tango Mango. IMHO, the best smelling of the 6, with strong citrus smells. Very lemon-y, but pleasant. - Eucamint. Ahhh, here's what was permiating out of the box. This smell is STRONG, with an AGGRESSIVE mint smell. Like, Ben Gay mint. And as strong to boot. It doesn't smell BAD, but it's hands down the strongest scent. - Oatmeal Shea. Meh. Kinda smells like an old coat that would be hanging in your grandfathers closet. It's not a BAD smell, but it has this weird odor to it, like when you leave a can of peanuts in your cupboard for a long time, and then go back and smell it. - Patchouli Lime. This one kind of smells like a mixture of Activated Charcoal, Eucamint and Oatmeal Shea. It smells like a room that you just painted a day or two ago, and it definitely has the Ben Gay after aroma lingering. - Apline Spice. This smells like a box. Like find an empty cardboard box, open it, and take a whiff. Boom, Alpine Spice. My least favorite. I will say, none of them STINK; as in there isn't a smell that I'm like, "ewww, I don't want to smell like AT ALL!" Which sounds weird, because I described some of them as "paint," "an old coat," and "a cardboard box," but I feel that those are just very passive smells, not aggressively bad ones. If there is a problem soap, I would assume it's going to be Eucamint, because it might just be too overpowering, although I've found that the more you smell them, they seem to mellow out. I imagine that after a shower with these, the smell will dissipate enough that it will be more mild. Still, with the exception of Tango Mango; a very good smelling soap mind you, I'd say they are all very "manly" scents, and I'm excited to try them out. Ok, so I'm a little over a week in, and here's my final take. (I made it through Activated Charcoal and Tango Mango): First, the scents ABSOLUTELY mellow out when used to actually shower with them. My wife, who admittedly isn't really up on me like that, hasn't even mentioned me smelling differently than the last 11 years. So, if she's even noticed, it's not on a level to make a fuss about. This is important because fresh from the box, these things have some powerful scents, but they are definitely tamed by washing with them. The bars last ABOUT 7 showers. Obviously, your mileage will vary based on how long you're in the shower, how much you scrub, how you store them, etc, but I was able to get 7 GOOD showers out of these. I have them in these natural sisal (whatever that is) exfoliating bags that help lather and store the soap, and really did some good scrubbing in my showers. The bars lather decently, but I'm not sure how much the bag helps with that. If you are a once a day showerer, a bar a week is a very fair approximation of what you'll get. I definitely felt.....SOMETHING I didn't before with my shower gel showers. I don't know if that's the moisturizing, or the exfoliation, but my skin felt a little different after showering. A decent buy. I'm not thrilled, but I'm not upset either. I don't think it changed my life, or even the way I shower, but I'm not mad at the experiment. I may try the Dr. Squatch soaps to see how all these stack up.

Convinced to make the switch
Style: Citrus
Love this soap. I was using Jukebox, but I'm making the switch. Crate 61 feels better on my skin, the bars last a little longer and the 6 pack is $15 cheaper than I was paying for 6 bars with the Jukebox subscription. I get extremely dirty at my job so I tend to go through soap faster than the average women. Jukebox bars would last me about 4 days. These will last 6 or 7 days. Jukebox bars were a definite upgrade from body wash, but it would irritate the sensitive areas. I don't have that issue with this soap. Jukebox bars smell nice in the shower, but I feel like the scent didn't last beyond that. Crate 61 leaves a pleasantly subtle smell on my skin after showering. The only benefit with Jukebox is that you can choose the individual soaps in your 6 pack, rather than selecting one of the collections.

Got more than I expected
Style: Boka 3.0
This is my first sonic toothbrush. I am very impressed with it. Like all the options it has and the look of it. It takes up a very small footprint and came with a vented brush cover. Their toothpaste and other products are excellent!
