Article: Agency Power 991 Carrera S muffler bypass pipes dyno - Save 30 pounds of weight and add 14 horsepower

[Sticky]

Introducing the Agency Power 991 Carrera S bypass pipes which are a nice and cost effective upgrade for the 991 Carrera S which save weight and add power. The baseline dyno was done on a Mustang Dyno and shows 344 rear wheel horsepower. The car is a PDK and this is less than we have seen on dynojets which is fairly common with Mustang dynos. The bypass pipes add 14 horses at the wheels which is certainly a nice gain. Graphs and video are below.
