This is a hexagonal muffler design constructed from lightweight titanium with a carbon-fibre outer sleeve, endcap, and heatshield. The distinctive Akrapovic sound has a deeper tone. The entry level in exhaust tuning offers improved torque and power throughout the whole rev range. The muffler is smaller than stock to offer a more striking and sporty appearance, and it weighs approximately 40% less than the standard exhaust. It is EC- and ECE-compliant, there is no need for remapping, and it has a simple plug-and-play installation.There are optional headers for improved torque and power in the mid range and high end of the power curve. If used with optional headers, remapping is needed.
