Rear silencer Capristo Porsche 911 GT2 RS 991

02PO03903020, 02PO03903039

Rear silencer for the Porsche 911 GT2 RS 991 with the MA1.71 3.8 biturbo flat-six. The GT2 RS is the most powerful 911 Porsche has built, and the factory exhaust is still sized for road homologation rather than for the engine.

Two versions

• Catless (02PO03903020);
• With 250 cell sport cats (02PO03903039).

The catless version flows most and is a track part; the 250 cell version keeps a working catalyst in the system.

What changes

On a turbocharged engine the restriction behind the turbochargers decides how quickly they unload. Opening it up changes spool and throttle response before anything is heard, and on an engine of this output the effect is not subtle.

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

• ECU programming may be required so no fault is set;
• The catless version is for off-road and track use;
• Installation uses the original mounting points and is reversible.

Capristo Automotive GmbH has built valved exhaust systems since 1990.
