Technical Description

In testing the 991.2 GT3 and RS we found the air intake to be restrictive, the 718 GT4RS shares a VERY similar engine architecture and the restriction at the throttle body is no different.  With the addition of the larger 93mm Throttle Body and Center Plenum you can allow the car to breathe better. 

We do the same analysis of the exhaust and tune the primary and secondary lengths, retain valves and built the most insane muffler to give the GT4RS the signature "GT3 wail" while maximizing torque and power (which isn't what everyone else does!).

Kit Includes:

Big Mouth GT4RS-specific Center Plenum

93mm Throttle Body

GT4RS Airbox Adapter

Adapter Harness

Tuned-length manifolds

Tuned-length “wave pipes”

High-flow cats

Valve sections (operate like stock valves)

Dundon V11 Muffler with stock tip adapters

Dyno of FULL D3 Exhaust and Intake package shown below compared to a stock GT4RS, nearly 40whp/trq gains! The car is an absolute monster in a straight line!
