As a hardcore Automotive enthusiast, I've tried numerous Exhaust systems & parts, but THIS one's a winner .As my tests showed, the baffling system packed within ample insulation offers a noise-cancellation feature second to none. Its all about that purr, and this muffer ensures that the passengers will be happy and noise pollution minimized. The only downside might be a slight decrease in horsepower due to the barrier thrown up between the engine and the outside environment. But that's a small price to pay for the satisfaction of a calm ride..
