Cobra Sport BMW M135i (F40) GPF/PPF Back Race Box Delete Exhaust

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 Gasoline Particulate Filter section backwards (GPF-back) replacing the centre and rear sections.

GPF Back with Box Delete Test Results:

Sound – Engine at Idle: 73.5dB (+10.5dB) – Static 3,800rpm test: 95.1dB (+13.1dB)

All relevant fittings and gaskets are supplied.

This exhaust offers a significant improvement in terms of exhaust tone, bass and sound level whilst keeping the stock catalyst and GPF in place.

This exhaust has a choice of 4″ (101.6mm) tailpipe options including a choice of carbon fibre tip options.

Please Note:

The ‘Valved’ exhaust retains the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will continue to swap from quieter to louder tones as before.

The ‘Non-Valved’ exhaust removes the use of exhaust valves. When switching drive modes (e.g. Eco to Race mode) your exhaust tone will not change from quieter to louder as before. Using a Non-Valved exhaust will not harm the running of your vehicle, you will simply not have exhaust sound options, however, the Cobra Sport exhaust has been designed with this in mind.

Press Release

The third generation of BMW’s 1 Series was launched in 2019, with the chassis name F40. For the performance range topping F40, BMW revived the ‘M135i’ moniker, which had not made an appearance on the back of a Baby BMW since its predecessor, the F20 M135i.

Sporting BMW’s B48 2 litre, 4-cylinder engine with Twin Power Turbo technology, the B48 produces 306hp and a thumping 332lb ft of torque. These punchy figures fire the M135i from 0-62MPH in just 4.8 seconds and on to an electronically limited top speed of 155 MPH. The M135i is shipped from the factory with a muted exhaust sound leading to a very disappointing driving experience.

Along with increased performance, Cobra Sport were keen to put the emotion back into the drive with an improved aural and emotional experience. Cobra Sport opted for 3”/76.2mm stainless steel pipework which is larger than most on the market for the biggest upgrade in terms of performance, flow rate and sound levels. The free-flowing Cobra Sport exhaust setup completely transforms the vehicle and will open up the future tuning possibilities of the BMW M135i (F40).

During the design stages, Cobra Sport made sure that all of the configurations are interchangeable so that customers can add to their system over the coming years. We imagine most will start with the PPF back configuration which can be fitted without the need for any engine tuning as it keeps the stock catalyst and PPF in place (MOT compliant). Adding a PPF delete section would create the cat back setup and customers going down the tuning route can add a high flow sports catalyst or de-cat front pipe to create a full turbo back setup.

For those who want further improve sound levels, Cobra Sport offers their unique rear silencer delete range. This exhaust setup removes the rear silencer to offer the biggest sound increase whilst keeping a sporty exhaust tone (+13.1dB in PPF back rear silencer delete configuration).

The Cobra Sport team were able to reduce the weight of the exhaust system by an impressive 49% over the OEM system with the PPF back rear silencer delete system weighing in at only 9.02kg compared to the original 17.8kg.

Cobra Sport have improved the styling of the BMW M135i, creating a noticeably enhanced and balanced look to the rear of the M135i with a choice of dual 4” (101.6mm) and 4.5” (114.3mm) slash cut highly polished stainless-steel tailpipes. For those looking to take the style upgrade a stage further, upgraded carbon fibre tailpipes are available.

Like all Cobra Sport exhausts, the M135i F40 exhausts are TIG-welded from high-quality T304 stainless steel and the mandrel pipework is a full 3” (76.2mm) in diameter for maximum sound and tuning potential.

Didn't help for sleep
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
First of all, I want to mention that I do think this is a quality product. Sea-based magnesium has had a good effect on me before and with the combination of AstraGin and avocado oil, this is a solid list of ingredients. AstraGin is a patented proven combo of notoginseng and Astragalus that helps with absorption in small doses. This was my first time trying AstraGin and I was unsure about using it for nighttime use due to the notoginseng, which is stimulating. But I have seen this in some other sleep formulas and they claim it's only meant for absorption and shouldn't stimulate. The first time I tried it at night with some of my usual supplements, I fell asleep easily but all of a sudden woke up 2 hours later and couldn't go back to sleep for 1.5 hrs. I only drifted back to sleeping bc I was so awake and had to resort to THC gummies. I took a couple days off and tried it again and it was the same bad sleep. Your experience might be different from mine because I am very sensitive to a lot of supplements and I think the AstraGin just doesn't agree with my system but I wanted to let other sensitive people know so they can be cautious.

Naturally sourced, quality magnesium softgels, with bioavailability and absorption support.
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
As someone who’s been using magnesium for years and likes to rotate between different forms like glycinate, bisglycinate, citrate, and L-threonate. I’m always on the lookout for magnesium supplements with smart formulas, especially those that prioritize bioavailability and absorption, since I’ve had issues with nutrient absorption in the past. This marine derived magnesium in softgel form really stood out to me, as I prefer softgels for bioavailability and absorption support. I’ve never been able to find a quality, natural, non-synthetic magnesium supplement in softgel form but I feel like I finally have.This aquamin magnesium was completely new to me and I found it genuinely refreshing, as it’s a break from the usual synthetic forms. You can tell right away this isn’t just another basic magnesium supplement. I’m impressed by this being a natural form of magnesium that contains 72 trace minerals that are naturally sourced from clean Irish seawater and sustainably harvested. I really appreciate the addition of avocado oil, as it helps support better absorption of magnesium. It's also a great source of healthy fats and antioxidants. Additionally this contains an ingredient completely new to me called AstraGin, which is naturally derived from astragalus and panax notoginseng. It was clinically shown to help support enhanced absorption. I really like seeing this in this supplement facts, it’s a big bonus for me, having nutrient absorption challenges. Although, anyone would benefit from high bioavailability and support for enhanced absorption. The focus on bioavailability and absorption was a big stand out, it’s exactly what I want to see in choosing a supplement. I usually use magnesium bisglycinate because of its high absorption, but this one actually claims even higher solubility compared to both glycinate and bisglycinate. A serving size of three oblong softgels provide 600 mg of magnesium sourced from sea water, 990 mg of avocado oil and 33 mg AstraGin. I love that my body is getting the support of a new form of magnesium that is natural and pure with the benefits of avocado oil and additional absorption support. healthy fats, I found three softgels easy to swallow, but I can see how these might be more challenging to have to take three of this size for a serving. I had no aftertaste or stomach upset, these seem very gentle overall. This is a high-quality magnesium supplement that's naturally sourced, with a focus on bioavailability and absorption support, that’s been clinically tested, and made with purity and transparency in mind. This is a true standout in my magnesium rotation. If you're looking for a magnesium supplement, I highly recommend trying it.

Most Illuminating Psych Book I've Read
Format: Hardcover
As a psychiatrist, I have yet to read a more illuminating book on how mental illnesses can develop, and how to help patients' to become free of them. Existential Psychotherapy presents a theory of the existential forces that drive all human beings--knowledge of death, of our aloneness in the world, and of "meaninglessness" (the utter inconsequence of our one life in the entirety of the universe). It shows how these forces are powerful influences in shaping human mental health and illness. Other reviewers here point out that the basic existential issues Yalom presents are well-known to academics and to many literate people who are exposed to them in that good, broad, liberal arts education we (still?) get in college. But what Yalom achieves in this book, has not to my knowledge been accomplished before (nor since): a presentation of these ideas to an audience of clinicians in a lucid, beautifully written, way that is salient to the daily practice of psychotherapy. Yalom is a rare psychiatrist who is not only a master of the art of teaching and practicing psychiatry, but for this book, ventured into philosophy, literature, history, and sociology, and then integrated the wisdom each brings to the study of human nature, into a clear and cohesive whole, a beautifully written theory of the existential dimension of men's fears, drives, and actions, and how this dimension creates mental illness or health, depending on how each person handles it. What is amazing is how such a book is now buried in the archives of (relative) obscurity, while others, recycling the same old tired ideas, reign on. So what do these lofty insights in Yalom's book contribute that is unique and powerful to us lowly practitioners toiling daily in our offices in the (seemingly more banal) task of helping patients with daily crises, complaints, resistance to change, and painful repetitions of self-destructive life choices? One very important tool: a true understanding of the power of existential concerns, not only in creating mental illness and self-destructive life paths, but, by shining a light on them-- capturing that elusive force of change: MOTIVATION. This force, and how to harness it to help patients overcome their suffering, has for me been one of my greatest challenges as a doctor. And one for which most books on psychotherapy have fallen short in helping me tackle. In the sections "death" and "will", (two of the four main sections in the book), Yalom forges a path that I could follow, to help my patients free themselves of the fears that block motivation for change. In short, Yalom shows how the anxiety about, (and thus avoidance of) awareness of our death and aloneness, can cripple us into denial, and resistance to changing those of our behaviors that shield us from these truths. But, these very fears, when faced and reframed--as the awareness of one's finite limits, and of the freedom that comes along with one's aloneness, become extremely potent engines for change. Other peoples' judgements, and fear of failure, lead us to believe that the human "judges" are the most important threat in our lives. But in Yalom's world, these feared judgements pale in comparison to the the consequences of inaction. When we live with acute awareness that we waste our only life when we are beholden to judges who are after all, mortal and alone just like us, this can shake us up to MOVE and LIVE, in this finite life, in a way other insights cannot. This example of how avoidance of existential fears leads to anxiety, low self-worth, and depression, is but one vignette in this book. Yalom applies his theory to the gamut of mental illness, and includes discussion of how narcissism, perversions, obssessions, masochism, sadism, ...the list goes on, are fueled by existential concerns. Yalom argues that they all boil down to one of two main strategies we humans employ to "forget" Death, Aloneness, and Meaninglessness: Either we escape too much into the protective cover of the GROUP, and become mindless group robots who drone through life until illness, or loss forces us to suddenly face our mortality, at which point many of us panic, or become depressed, OR, we get sucked into this defiant delusion : "I am SPECIAL"...smarter, more rebellious, unfettered by the social conventions of meek men, thus free of death's jaws". This reaction then can lead to reckless, impulsive, pseudo "powerful" behaviors that are often the fuel of many "acting out" mental problems: addiction, sociopathy, sadism, and narcissism. Enough of my words-read and feel the power of Yalom's words in this great book.
