Rear silencer Capristo Porsche 911 Turbo / Turbo S 997 MK2

02PO01203003

Rear silencer for the Porsche 911 Turbo and Turbo S 997 MK2 with the MA1.70 3.8 biturbo flat-six. The MK2 was the first 997 Turbo with direct injection and variable turbine geometry, and the standard rear silencer is the main restriction left behind it.

How it works

The silencer uses a shorter gas path and less damping volume than the original, so the flat-six reaches the tailpipes with far less filtering. On a turbocharged engine the turbochargers already absorb part of the exhaust note, which is exactly why opening up the rear section is what brings the sound back.

Material and build

T309 (1.4828) stainless steel, rated for continuous temperatures above 600 C, hand TIG welded and polished to a mirror finish in Sundern, Germany, developed on 3D laser scans of the original part.

Before you order

• The article is for the MK2 cars, the earlier 997 Turbo uses a different one;
• Stainless steel does not rust, unlike the original silencer shell;
• The silencer is lighter than the standard box;
• Installation uses the original mounting points and is reversible.
