style="text-indent:25px">消音器的改裝管按材料來分可以分為鋁合金摩托車排氣管，不銹鋼摩托車排氣管，碳纖維摩托車排氣管，鈦合金摩托車排氣管等等，各有千秋。鋁合金的管重量比較輕，顏色也多，價格也比較便宜，但是管的表面容易磨損，不及不銹鋼的管耐用。不銹鋼的管重量比較重，顏色也少，但它比較耐用，聲音比鋁合金的管沉些，所以一般玩改裝的朋友都喜歡選不銹鋼的管。不過材料本身價格較高，還是無法讓其真正高度普及化。碳纖維的管重量比較輕，一般都是黑色碳纖維為主，耐用度也比不上不銹鋼的。</p><p style="text-indent:25px">汽車排氣管里的消聲器的原理：就是通過降低、衰減排氣壓力的脈動來消除噪聲。根據(jù)干涉原理，排氣消聲器有吸收、反射兩種基本的消聲方式。吸收式消聲器，通過廢氣在玻璃纖維、鋼纖維和石棉等吸音材料上的摩擦而減小其能量；反射式消聲器則有多個串聯(lián)的諧調(diào)腔與不同長度的多孔反射管相互連接在一起，廢氣在其中經(jīng)過多次的反射、碰撞、膨脹、冷卻而降低其壓力，減輕振動及能量。實際情況下，汽車上多是綜合利用不同的消聲原理組合來設(shè)計排氣消聲器，同時在舒適型要求較高的小型乘用車上還會采用多個消聲器單元進(jìn)行多級的消聲降噪控制。消聲器一般由排氣管、連接螺套、消聲筒和筒芯等幾部分組成。</p><div
