Slip-On Line (Titanium) S-BM/T/15H

Brand: Akrapovic


Upgrade the performance and the sound of your BMW M135i with the Slip-On Line (Titanium) S-BM/T/15H exhaust system from Akrapovic. This beautifully crafted exhaust system is made of high-grade titanium and is designed to deliver a full-on sensory experience for the driver and passengers. The carbon-fibre tailpipes add an eye-catching touch to your car's rear end, making it stand out from the crowd. One of the unique selling points of this exhaust system is the in-house cast exhaust valve housing, which gives the exhaust a rich and deep tone without any discomfort or drone for the occupants. The sound is further enhanced when shifting through gears, with an emphasis on high frequencies. The specially engineered Y-split reduces flow noise without any compromise to the pressure pulse distribution, providing a strong sound and optimal flow path. But the benefits of the Slip-On Line (Titanium) S-BM/T/15H exhaust system go beyond just the sound. 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. This reduction in weight translates to improved performance, with power increased by 3.3 kW (4.5 hp) at 5,350 rpm and torque up by 5.9 Nm at 5,300 rpm. Akrapovic is a renowned manufacturer of high-performance exhaust systems, and this product is no exception. The design and construction of the exhaust optimize the power and torque levels throughout the rev range, providing a noticeable improvement in performance. 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. Installation of the Slip-On Line (Titanium) S-BM/T/15H exhaust system is easy and straightforward, with no modifications required. The exhaust system is specifically designed for the BMW M135i XDrive model, ensuring compatibility and a perfect fit. For those looking for even further upgrades, an optional Evolution Link pipe set (SS) is available. Upgrade your BMW M135i with the Slip-On Line (Titanium) S-BM/T/15H exhaust system from Akrapovic and experience the benefits of improved performance and a deep, rich sound. With its lightweight materials, easy installation, and compatibility with the BMW M135i XDrive model, this exhaust system is the perfect choice for any discerning driver looking to enhance their car's performance and sound.
