Ferrita Sweden AB Turns to Additive Manufacturing for a 2003 Mercedes-Benz SLR McLaren Exhaust Project

Ferrita Sweden AB specializes in advanced technical solutions in sound attenuation, vibration, thermal insulation, and exhaust gas purification. That combination of capabilities was put to the test when a customer brought in a 2003 Mercedes-Benz SLR McLaren — a hand-built supercharged V8 dream car — for refinement.

A Front Fender Doing the Work of an Exhaust Bay

The engineering constraints on the Mercedes-Benz SLR McLaren project were severe. New components had to be designed to perfectly match the existing lines of the vehicle. Complicating matters further, the original manufacturer had installed an entire exhaust system inside the front fender — a packaging decision that effectively defined the design envelope before Ferrita's team touched a single part.

The hardware itself added to the challenge. The original muffler was heavy, and the exhaust system presented considerations around complex fluid dynamics and back pressure. On top of all of this, the customer wanted their car back within 1 week.

Taken together — precise geometric matching, fender-installed packaging, a heavy baseline muffler, fluid dynamics and back-pressure concerns, and a 1-week turnaround — this was a demanding brief by any engineering standard.

The Additive Decision

Ferrita Sweden AB turned to additive manufacturing for the project.

The decision is notable for where it lands: additive manufacturing applied to an exhaust refinement on a hand-built supercharged V8 dream car, under constraints that touched geometry, mass, and schedule simultaneously. For a company whose stated specialties span sound attenuation, vibration, thermal insulation, and exhaust gas purification, the Mercedes-Benz SLR McLaren project sits squarely in Ferrita Sweden AB's technical wheelhouse — and additive manufacturing was the route its team chose to take it on.
