Product Description
Independent Rear Suspension, or IRS as it’s commonly known, was introduced in the VP Commodore as standard on the Calais and SS, and an option on lower models. Due to the radically different suspension setup when compared to the live axle models, the cat-back section of the exhaust is also different, running underneath the axle rather than over it. The Manta exhaust for the VR and VP IRS V6 Commodore comes in a number of configurations, each giving increased performance and varying levels of sound.
The 2.5″ pipe size is the perfect match for the V6 motor, giving good low-down power and torque, while also providing enough flow at higher RPM’s. Fitting a set of extractors and a high flow cat offers the most benefits for the vehicle, while a cat-back system is excellent if you are chasing an improved exhaust note. All exhaust systems use high-flow mufflers to control the exhaust noise without impeding performance in any way. Our aluminised steel systems offer good value for money, while still carrying a 2 year warranty.
