Product details
The Maxflo side-muffler assembly changes the rear side silencers on a Porsche 991 Carrera while leaving the center exhaust choice to suit the build. It offers a deeper tone, but the remaining factory center silencer has a significant influence on the final sound. Fabspeed Motorsport is based in Fort Washington, Pennsylvania, where it develops exhaust, intake and ECU-tuning products for Porsche and other sports cars. Its development work includes dynamometer testing and evaluation on the road and racetrack.
Before you order
Confirm which 34/38 tip-option code matches your engine and original exhaust before ordering. Those codes should not be selected by appearance alone.
