The 5.7L LS1 V8 introduced in the VT Series 2 Commodore, and found in the WH Statesman and Caprice, was the first of a long line of American built Chevy V8’s to be fitted to the Commodore family. Initially producing 230kw, the motor was greatly restricted by the stock exhaust system, which also gave the Commodore 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 twin 2.5″ has a throaty and deep sound, while the dual 3″ is the ultimate system available for the V8 Statesman. It gives the greatest flow, and the resulting 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.
