991.1 GT3 Cup racing exhaust manifold replacement tailpipes optional heat protection for Porsche 911

991.1 GT3 Cup racing exhaust with manifolds and interchangeable tailpipes optionally with heat protection for Porsche 911.
The system is available with or without heat protection. The image shows the system with heat protection.

This system was developed to significantly reduce the noise of the 991 GT3 Cup racing cars.
The noise level of this system, measured directly behind the silencer, is less than 98 dBa.
Depending on the measuring method (e.g. in Zandvoort), only 91.5 dBa is measured on our vehicles.
In addition, this system includes 2 interchangeable tailpipes which further reduce the sound by approximately -2 dBa.
This makes it the quietest system available on the global market for a 991.1 GT3 Cup.
