Akrapovič Exhaust Systems – Frequently Asked Questions

The Akrapovič Slip-On Line is designed for drivers looking to enhance sound character, reduce weight, and improve aesthetics while retaining the vehicle’s factory emissions systems. These systems focus on the rear section of the exhaust and deliver a noticeable improvement in acoustics without altering emissions-related components.

The Akrapovič Evolution Line is intended for those seeking the highest level of performance enhancement and a deeper, more pronounced exhaust note. It builds upon the Slip-On Line by incorporating additional high-performance components such as link pipe sets or header sets. Due to the increased airflow and system changes, an ECU recalibration is almost always required to ensure optimal engine operation.

Akrapovič exhaust systems are developed modularly, allowing vehicles fitted with a Slip-On Line to be upgraded to an Evolution Line at a later stage if further enhancements are desired.

The Akrapovič Sound Kit is an advanced accessory that allows drivers to manually control the exhaust valves of compatible Akrapovič exhaust systems, independent of the vehicle’s factory drive mode settings.

Using either a Bluetooth remote control or a smartphone application, the Sound Kit enables the driver to open or close the exhaust valves at will. This allows for a quieter exhaust note in urban or residential environments, and a more expressive, dynamic sound when conditions allow, without needing to change the vehicle’s selected driving mode.

The Sound Kit is designed for drivers who value flexibility and personalisation, offering full control over the exhaust sound profile in different driving scenarios.

Mandatory components vary depending on the specific vehicle model and derivative. In many cases, tailpipes are required unless they are already integrated into the exhaust system being purchased.

Certain applications may also require additional mounting hardware, specific OEM components, or, less commonly, a compatible rear diffuser to ensure correct fitment and alignment. Because requirements can differ between vehicle variants, professional verification before installation is essential.

As an authorised Akrapovič retailer and installer, R44 Performance confirms all required mandatory components prior to purchase to ensure correct compatibility and installation.

Akrapovič exhaust systems should always be installed by authorised and trained specialists to ensure correct fitment, functionality, and warranty compliance.

R44 Performance is a licensed Akrapovič installer based in London, providing professional installation services for UK customers as well as technical support for international clients. Our technicians are trained specifically on Akrapovič systems and their integration with modern vehicle electronics, particularly on BMW platforms.

The installation process varies depending on the exhaust system and vehicle. Some systems are fully bolt-on, while others may require modification of the original exhaust to ensure precise fitment.

Due to the precision engineering of Akrapovič exhaust systems, installations are carried out by experienced technicians who understand vehicle-specific requirements, exhaust valve integration, and thermal clearances. This ensures correct operation, long-term reliability, and optimal sound characteristics.

Installation time depends on the vehicle model and the specific Akrapovič system being fitted. Simple Slip-On systems may take only a few hours, while full Evolution Line systems can require additional time, particularly if calibration or supplementary components are involved.

For accurate time estimates, it is recommended to discuss installation requirements with your authorised Akrapovič specialist in advance.

Slip-On Line exhaust systems are typically designed to work with the factory ECU configuration and do not usually require recalibration.

Evolution Line systems, which include additional performance-focused components, almost always require an ECU remap to ensure the engine operates correctly with the increased exhaust flow. This is essential for maintaining drivability, reliability, and optimal performance.

Akrapovič exhaust systems are covered by a comprehensive manufacturer warranty, reflecting the brand’s rigorous testing standards and exceptional build quality.

The warranty covers manufacturing defects in materials and workmanship, with defective parts replaced where applicable. The standard warranty period is typically two years from the date of installation and is transferable, subject to regional terms and conditions.

The warranty does not cover damage caused by normal wear and tear, misuse, accidental damage, improper installation, or unauthorised modifications. Installation by an authorised Akrapovič dealer or technician is required to maintain warranty validity.

To ensure authenticity, Akrapovič exhaust systems should only be purchased from authorised retailers. Buying through unauthorised sources can risk counterfeit products, missing components, or invalid warranty coverage.
