Overview

The 991.2 GT2RS is Porsche's most extreme, most powerful, and most uncompromising street 911. 700 horsepower. Rear-wheel drive only. A 3.8L twin-turbocharged flat-six that operates at the absolute limit of what a road car can be. The "Widowmaker" earned its reputation - and it deserves an exhaust that matches its ferocity.

Connecting to OEM or aftermarket downpipes, this system runs 2.5 inches from inlet to outlet. Exiting via brushed single-wall Valvetronic tips.
