One way you might want try are with mufflers that will give you that sound. I remember how powerful those old cars sounded. But if you take the cars we have now and you compare them, the new cars sound like wimps. They may have higher performance engines but they just do not sound like it.
Having a car that growls when the engine is running is sweet noise to my ears. Compared to the quiet of most cars on the road today, the sound of those muscles cars will certainly draw attention. Don’t get me wrong, I like today’s cars and the fact that they get better gas mileage, but I miss the sound of those old muscle cars. You knew you were driving something with a lot of power. Silence may be golden, but give me the growls and roars of a powerful sounding engine. Let me hear the power.
