Akrapovic Exhausts for Porsche

How to choose an Akrapovic exhaust for your Porsche

Slip-On Line, Slip-On Race Line, Evolution Line and headers

Akrapovic describes the Slip-On Line as the first step in exhaust tuning, and on the GT3 it fits directly onto the car's original system. The Slip-On Race Line is the more track-focused version. The Cayenne systems here are Evolution Lines, supplied with their own tailpipes, and the Panamera has both Slip-On Lines and an Evolution Line. Link pipe sets join the Slip-On or Slip-On Race Line, most with sport catalytic converters, and Akrapovic says its Evolution header sets turn the Slip-On into a full exhaust system.

OPF cars and road approval

The OPF, or GPF, is the petrol particulate filter. Many product pages say whether a part suits OPF cars, non-OPF cars or both. The 911 Carrera and Turbo (992) Slip-On Race Lines fit both, for example, while the Panamera (971) Slip-On Lines and the non-OPF Cayenne (536.1) Evolution Line do not fit OPF cars. If you are unsure which your car has, check its specification or contact us before you order.

Akrapovic lists ECE type approval for the Slip-On Line on the 911 GT3 and GT3 RS (997), GT3 (991.1) and GT3 RS (991.2), the Cayenne and Cayenne E-Hybrid (536.1) Evolution Lines, the Panamera (971) Evolution Line and the Panamera (976) Slip-On Line. Approval can lapse: on the GT3 RS (991.2) it ends once link pipes or headers are added, the Cayenne and Panamera sound kits invalidate it, and the Panamera (971) certificate is not valid on OPF cars. Every header set here, and almost every link pipe set and Slip-On Race Line, is listed for closed-circuit or track use only. Where a page states no approval, ask us rather than assume.

Remaps and required parts

Akrapovic says no ECU remap is needed for the 911 GT3 (992) Slip-On Race Line, the 718 Cayman GT4 RS Slip-On Race Line on its own, or the Panamera (971) Slip-On and Evolution Lines. It lists a remap as mandatory for its header sets and most link pipe sets, in some cases only on OPF cars.

Some systems need companion parts. The 911 GT3 RS (991.2) Slip-On Line and Slip-On Race Line need a separate tailpipe set, and the OPF version of that Slip-On Line also needs the Evolution Header Set. The 911 Turbo (991.2) Slip-On Line needs the carbon fibre rear diffuser. The Cayenne, E-Hybrid and S E-Hybrid (536.2) Evolution Line needs a fitting kit on cars without Porsche Sport Exhaust, and the Panamera (971) Evolution Line needs the Middle Valve Controller Kit on cars with the base exhaust. Our 911 Turbo and GT3 (992) Slip-On Race Line listings already include the tailpipes or adapter set Akrapovic requires.
