say what? The Corsa muffler is also a straight though, with a perfertated pipe, but the insides are totally different. No padding, just a series of v-shaped baffles to break up the sound waves. Well, more accurately, reflect the waves back into themselves, canceling out the noise. The cause of the resonance is the shape of the C4 cabin itself. The storage area is its own resonance chamber. |
