  Akrapovic TITANIUM EVOLUTION SYSTEMDISCONTINUED
The Evolution system represents the top line of Akrapovic aftermarket exhaust systems for Porsche's bestseller.

  Akrapovic slip-on 911 (991) Carrera Cabriolet /S/4/4S/GTSS-PO991SO-HT
The challenge of designing a system for the 911 is always going to be one of the most demanding. Very little space and short exhaust runs mean that any systems developed have very little space to fit all necessary components. The design team at Akrapovic have been working their magic to produce the new Akrapovic 991 slip on system. The new system features dual note active valve system so at the push of a button the 991's flat six engine can be heard on full song with race inspired sound track. Made from Akrapovic's titanium alloys the new system not only delievers an additional 18 bhp but saves nearly 10kg of weight over the stock Porsche system.GSP Price:
