400hp Grand Prix idle
Not all high horsepower 3800s have to be loud. This 340whp setup runs a stock Exhaust, stock manifolds, an engine that hasn't been cracked open, gets 28mpg on the expressway and even has luxuries like navigation and bluetooth. Whether you want loud and ostentatious or quiet and subdued we can get your 3800 set up.
