Akrapovič Porsche 911 (991.2) Turbo/S Slip-On Line Titanium
Akrapovič Slip-On Line sports exhaust system dedicated to the Porsche 911 (991.2) Turbo/S
Design and materials
The Slip-On Line is the first stage of the exhaust modifications of the Porsche 911 Turbo and Turbo S generation 991.2. The titanium end section is complemented by titanium tips located on both sides of the rear of the body.
The required diffuser is handcrafted from carbon fiber and available in matte or gloss finishes. Its shape is designed specifically for the car and the arrangement of the Akrapovič tips, creating a common configuration of the exhaust and rear trim.
Finish Configuration
A complete Slip-On requires a selection of titanium tips along with a suitable carbon diffuser. These elements work together in terms of the shape and position of the outlets.

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.
