This product was developed using our vast knowledge from previous generations of aftermarket exhaust systems for Porsche Panamera models. It is constructed from high-grade lightweight titanium, with parts manufactured at the in-house foundry, including the exhaust valve housing. It is finished with newly designed handmade carbon-fibre tailpipes with acoustic reflectors, designed to reflect the external sound toward the cabin. The sound is regulated by a specially developed control kit, which uses valves to provide the optimal sound experience of an Akrapovic exhaust in all drive modes, without compromising comfort. It delivers a rich high-frequency sound with a sporty note for V6 models, and the V8 versions create an orchestral harmonic rumble with a sporty note as the revs rise. Both engines produce a smooth tone through the exhaust without any drone for maximum everyday comfort. The exhaust system offers a substantial weight saving of 46% (8.6 kg) over the V8 sport stock version and 44.5% (8.3 kg) over the V6 sport stock system. The Slip-On Line (Titanium) installed on the Porsche Panamera Turbo S E-Hybrid produced an increase in power of 7.1 kW (9.7 hp) at 6450 rpm and a torque gain of 11 Nm at 5150 rpm when tested on The Akrapovic dyno against the equivalent car fitted with a sport stock exhaust system
