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.

Better than expected
Color: Stainless Steel, Color: Stainless Steel
I have to say, it has completely transformed my kitchen countertop organization. From the moment I unboxed it, the quality and thoughtfulness of the design were immediately apparent. The stainless steel construction feels extremely sturdy and durable, giving the holder a sleek, modern look that complements any kitchen décor. Unlike lighter, flimsier holders, this one feels solid and well-balanced, thanks to the weighted, non-slip base, which ensures it stays put even when tearing off a single sheet with one hand. The spring-loaded tension arm is an absolute game-changer. I can tear off a paper towel effortlessly with just one hand, which is perfect when I’m cooking, cleaning, or juggling multiple tasks. No more awkward pulling or having to stabilize the roll with my other hand—it makes the process smooth and frustration-free. One of my favorite features is the integrated spray bottle. Having a cleaning solution right on the holder is incredibly convenient. I can quickly grab the paper towel and spray my countertops or stovetop without having to search for a separate bottle, which makes daily cleaning routines much more efficient. The spray bottle is easy to refill, and the design keeps it snug and stable so it doesn’t tip over. Setup was a breeze it came fully assembled, so I could start using it immediately. The overall footprint is compact, so it doesn’t take up much counter space, but it still accommodates standard-sized paper towel rolls comfortably. Even larger rolls fit without any problem, and the holder handles the weight without wobbling. Overall, the Ultrean Paper Towel Holder with Spray Bottle combines functionality, durability, and style in one package. It’s perfect for busy kitchens, whether you’re cooking, cleaning, or entertaining guests. The convenience of one-handed tear, combined with the integrated spray bottle and sturdy base, makes it worth every penny. I’ve found myself reaching for it constantly, and it’s made my kitchen workflow so much smoother. Highly recommended for anyone looking to elevate their kitchen organization while adding a practical and stylish accessory.
