Product Information

Beautifully crafted from high-grade titanium, this lightweight exhaust system for the F40 M135i xDrive and F39 X2 M35i is finished with eye-catching carbon-fibre tailpipes and is a full-on sensory delight. The exhaust valve – with its housing cast in the in-house foundry – gives the exhaust a rich sound with an emphasis on high frequencies, especially when shifting through the gears, all allied to a deep tone that enhances the car’s engine without any discomfort or drone for the occupants. A specially engineered Y-split reduces the flow noise without any compromise to the pressure pulse distribution, thus offering a strong sound and optimal flow path. The use of lightweight materials and a different configuration reduces the overall weight of the exhaust by 9.4 kg, a saving of 55.6% on the stock version. The design and construction of the exhaust optimize the power and torque levels throughout the rev range, with performance increased by 3.3 kW (4.5 hp) at 5,350 rpm and torque up by 5.9 Nm at 5,300 rpm. This was achieved during in-house tests with back-to-back runs on the Akrapovič dyno against a BMW M135i using a standard stock exhaust. For a further upgrade of the Slip-On Line (Titanium) exhaust system, an optional Evolution Link pipe set (SS) is available (M135i xDrive only).

The exhaust system is ECE type approved for cars equipped with an Otto/gasoline particulate filter.

To install the Slip-On Line (Titanium) exhaust system, the stock exhaust system must be cut; please read the instructions carefully before the start of the installation.

Suitable for F40 M135i xDrive Hatch and F39 X2 M35i models with or without OPF/PPF.

One of (if not THE most) professional outfits I’ve dealt with - in the auto industry or otherwise. Needless to say, all work was carried out as promised and to an impeccable standard. Thank you Sean and team - you’ve renewed my faith in the auto business!

First time at Southern BM today and it won't be my last. Efficient and quality service as I'd expected at a much more reasonable price than a BMW Dealer. The only downside, you'll drop your car off and will end up drooling over the m3s and m4s out front!
