Akrapovič Porsche 911 GT3 (991) Slip-on Race Line Titanium
Akrapovič Slip-on Line sports exhaust system dedicated to the Porsche 911 GT3 / GT3 RS generation 991
Design and materials
The Slip-On Race is made of high-grade titanium as the first stage of an expansion of the Porsche GT3 production system. The design reduces weight and works in tandem with the car's original front section.
The finish is provided by distinctive twin round titanium tips. The required TP-T/S/19 kit is a separately selected element of this configuration.
Sound characteristics
The titanium Slip-On gives the engine its distinctive, sporty Akrapovič tone. It is the basis for further shaping the sound through the selection of the connecting section or manifolds.
Expansion Options & Accessories
A carbon fiber diffuser is also available to order to complement the modifications.
Upgrade options
Optional titanium Link Pipe Set retains stock manifolds and replaces side dampers. A full layout can be built with the Evolution Race Header Set without valves or the Evolution Header Set with side dampers and valves.

Akrapovič creates performance exhaust systems that combine lightweight construction with carefully developed sound. Depending on the application, the brand uses titanium, stainless steel and carbon-fibre components.
An in-house titanium foundry and materials laboratory support control over key stages of exhaust production. Akrapovic is an option for sports car owners who value component weight, craftsmanship and distinctive tailpipe detailing.
Akrapovič quality control includes alloy composition, mechanical properties and weld analysis. Prototype measurements use optical scanning and coordinate measuring equipment. Sound development combines road testing, dynamometer work, flow measurements and acoustic simulations.
History and development. Akrapovič was founded in 1991, with its development rooted in motorcycle racing. Milestones included entering MotoGP in 2002, opening its own titanium foundry in 2009 and adding a second factory in 2014.
The business today. The company now manufactures motorcycle and performance-car exhausts in Slovenia for aftermarket customers and OEM partners. Racing-team support remains part of its operations. Its laboratories, foundry and manufacturing facilities enable materials research and acoustic development to take place within the business rather than relying solely on external suppliers.
