Description
Manufactured to exacting specifications from high-grade titanium – with parts cast in Akrapovic’s in-house foundry – this system utilises lightweight materials to reduce overall vehicle weight and optimize power and torque through the entire rev range. Meeting ECE type approval, the design of the system fully adapts to the lines of the car, and the single-muffler layout with four superb hand-crafted carbon-fibre round tailpipes give a distinctive look to the rear of the car. Various sound modes add to the experience, with a sporty and animated roar from the six-cylinder engine when the revs rise, and a more pleasing experience in comfort mode, ideal for cruising with the roof down.
An optional Akrapovic Sound Kit is available to control the various sound settings, and optional tuning opportunities exist through the addition of the stainless-steel Evolution Link Pipe set. As with the Sound Kit, fitting the Link Pipe will negate the ECE type approval.
Fitment and EC type-approval are valid for engine type B58B30C. ECE type approval is only valid for cars equipped with otto/gasoline particulate filter.
For installing the slip-on system, the stock exhaust system has to be cut. Please read the instructions carefully before the start of the installation.
