Not only is the tone improved but the additional burbles and pops that come with it are simply intoxicating. Dinan also incorporates a Helmholtz chamber design that reduces resonance or\"drone\" at low RPM.\u003c\/p\u003e\u003cp\u003eThe system is built to exacting specifications to ensure the perfect fit using the factory hangers.
