Exhaust system Capristo Porsche 911 Turbo / Turbo S 991

02PO03903001, 02PO03903037

Exhaust system for the Porsche 911 Turbo and Turbo S 991 with the MA1.70 and MA1.71 biturbo flat-six. On a turbocharged 911 the turbochargers absorb a large part of the exhaust note before it even reaches the silencer, which is why the section behind them matters so much.

Two versions

• With the CES-3 controller and ECE approval (02PO03903001);
• With 250 cell sport cats and the CES-3 controller (02PO03903037).

The second takes the catalyst section with it, so the restriction is removed in front of the silencer as well as behind it.

How it works

The CES-3 is back pressure monitored and programmable, with the threshold set by the owner. Closed, cruising noise stays civil; open, the path shortens and the flat-six comes through with much less filtering.

Material and build

T309 (1.4828) stainless steel, rated above 600 C, hand TIG welded and polished to a mirror finish in Sundern, Germany.

Before you order

• The ECE version keeps the car street legal in Europe;
• ECU programming may be required with the sport cat version;
• Installation uses the original mounting points and is reversible.
