One Week, One Fender, One Supercharged V8: Ferrita Takes on the SLR McLaren

An Unusual Job in Sweden

Ferrita Sweden AB is a manufacturer of advanced technical solutions in sound attenuation, vibration, thermal insulation, and exhaust gas purification. It is also a company that allows its team to be highly creative with exhaust design. Both traits were put to the test when a customer brought in a 2003 Mercedes-Benz SLR McLaren for refinement.

This was no ordinary vehicle. The project involved a hand-built supercharged V8 dream car — and the engineering constraints on the Mercedes-Benz SLR McLaren project were severe.

The Constraints Stack Up

Consider what Ferrita was up against. New components had to be designed to perfectly match the existing lines of the vehicle. The original manufacturer had installed an entire exhaust system inside the front fender of the Mercedes-Benz SLR McLaren — an unconventional packaging decision that left little room for standard fabrication approaches.

Then came the physics. The original muffler was heavy, and the exhaust system presented considerations around complex fluid dynamics and back pressure. Any redesign had to respect those realities, not fight them.

And the clock was running: the customer wanted their car back within a week.

The Additive Answer

Faced with tight packaging, demanding flow requirements, and a one-week turnaround, Ferrita Sweden AB turned to additive manufacturing for the project.

The logic is straightforward for anyone who has worked around a compressed build schedule. When components must follow existing body lines exactly, fit inside an enclosure as tight as a front fender, and satisfy fluid dynamics and back pressure requirements, conventional tooling timelines become the bottleneck. Additive manufacturing offered Ferrita a path around that constraint — a way to go from design intent to physical component within the window the customer allowed.

For a company whose business spans sound attenuation, vibration, thermal insulation, and exhaust gas purification, the project sits squarely in its technical wheelhouse. The difference here was the canvas: a hand-built supercharged V8 dream car, and just one week to refine it.
