The Rennline GT3 Titanium Exhaust is a direct replacement for the factory rear muffler on the 4.0L 991.2 GT3, GT3 RS, 911 R, and Speedster. It bolts into the OEM location in place of part number 991 111 027 90, with no cutting or modification required.
Fabricated entirely from titanium, the same material as the factory muffler it replaces, it is exceptionally light at 12lbs. It ships as a complete, ready-to-install kit: the system comes with its exhaust tips, mounting flanges, and gaskets, so everything needed to fit it is in the box.
