Built from hi-grade titanium and finished with two eye-catching double round tailpipes, this entry system makes the GT3 more powerful and lighter, and gives the car that unique Akrapovič sound. Designed to make the car stand out from the crowd and increase its appeal even more, the visual delight of the Akrapovič Slip-On can be further enhanced with the addition of an optional carbon- fibre rear diffuser. Beautifully handcrafted from the finest materials and designed to enrich the exclusive look of the titanium exhaust system, the diffuser is a must-have extra for any discerning owner.
