Description

DETAILS
A lighter weight system that has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing the sound.
This is an Active Valved system which is designed to perfectly replace the existing setup thus retaining all functionality within the vehicle.
The sport system helps unleash the 4.0 litre V8’s potential. The internals have been completely redesigned to offer a more distinct difference in sound when the valves open and shut. The system also accentuates all the elements of this wonderful engine with its t urbo whistles, deep  guttural V8 bass and pops and crackles on the over run. In combination with our OPF/GPF delete pipes the sound reaches a crescendo for all to enjoy.
SOUND ARCHITECT™
Electronic/Pneumatic Valves – Retains OEM (in-car) functionality
Our active valve sport exhaust systems contain two separate gas paths, and an electronic or pneumatic flap-valve that decides which path is taken. Both have two distinct levels of sound and are slightly louder than stock. With the valves closed, the system takes on a more civilised note and when they’re open, you’re given a sporty note throughout the rev range.
These valves are integrated into the car’s existing controls and function depending on the ECU mapping. This can then be further manipulated either with the dedicated exhaust button or by switching the driving modes.
KEY FEATURES
• Deep muscle rich V8 sound.
