Remus 2018 BMW Z4 M40I Roadster 3.0L Turbo (B58B30C R6 w/GPF) Axle Back Exhaust (Tail Pipes Req)

This Remus axle-back exhaust system is made for the 2018 BMW Z4 M40i Roadster with the 3.0L Turbo B58B30C R6 engine, specifically models equipped with a GPF (Gasoline Particulate Filter). It replaces the factory muffler section, offering a more engaging sound and a sportier feel to your driving experience. Remus is well-known for crafting exhaust systems that balance performance with a refined tone, and this axle-back is designed to enhance the character of your Z4's engine without being overly aggressive for daily driving.

Constructed from well-built stainless steel, this exhaust is designed to resist corrosion and maintain its appearance over time. The system is engineered to bolt directly onto the factory exhaust piping, making installation straightforward for those comfortable working on their vehicle. While this axle-back unit replaces the muffler, it's important to note that it requires the use of the factory tailpipes or compatible aftermarket ones, as they are not included with this specific part number. This allows for some customization in the final look of your Z4's rear end.

When installing this axle-back exhaust, you can expect a noticeable change in the exhaust note, typically a deeper, more resonant tone under acceleration and a sportier growl when you lift off the throttle. The system is designed to work with the factory catalytic converter and GPF, ensuring it meets emissions standards for the intended application. For the best results and a seamless installation, it's always recommended to refer to the manufacturer's installation instructions, which will detail any specific requirements or torque specifications.
