The Sound of the Porsche 992 GT3 with Lettieri Exhaust

By Fausto Lettieri·March 17, 2026

The Perfect Sound

When a client asked us to create an exhaust for his Porsche 992 GT3, we knew the challenge was immense. The GT3's flat-six is already a symphony, but we wanted to take it to the next level.

The Challenge

The 992 GT3's 4.0-liter engine produces a naturally satisfying sound, but the original exhaust system is designed to meet increasingly strict regulations. Our goal was to unleash that voice without sacrificing anything.

The Solution

We developed a complete system featuring:
  • 4-2-1 Headers in AISI 304 stainless steel
  • Sport mufflers with electronic valves
  • 90mm carbon fiber tips
  • The Result

    108 dB in open mode, 92 dB in comfort mode. The best of both worlds.
    "I've never heard a GT3 sound like this. It's pure emotion." - Marco, owner
