The 5.7L LS1 V8 introduced in the VY HSV Sedan, was a high output version of the motor found in regular Commodores. Producing 260kw, the motor was still restricted by the stock exhaust system, which also gave the car a somewhat muted exhaust note. By fitting a Manta exhaust system, the true character of the GenIII V8 can be released, together with extra power, torque and responsiveness. There are a number of options to suit all requirements, tastes, and budgets. A cat-back system is the ideal choice if you're after improved sound, while a full system will give the maximum increase in performance, and also improve the exhaust note, making it crisper and louder. The dual 2.5" is a great choice if you are chasing better sound, and improved performance, while the dual 3" is the ultimate system available for the V8 Commodore, giving the greatest flow, and a roaring unbridled exhaust note that will send any enthusiast into raptures. All systems are available in aluminised steel, or for the ultimate in longevity, stainless steel which carries a 10 year warranty.
