distance than the exhaust pipe extending from the rearwardly disposed manifold exhaust gas noise is defined by a plurality of discrete pulses corresponding respectively to the firings of the cylinders attenuation of the exhaust gas noise can be carried out most efficiently if the respective pulses arrive at the muffler sequentially however unequal travel lengths for exhaust gas flowing from two separate banks of cylinders can result in some noise pulses from one bank of cylinders overlapping and adding to noise pulses generated by the other bank of cylinders these combined noise patterns may not be adequately attenuated by the muffler as shown in fig1 the non symmetrical alignment of the exhaust system 12 results in the first upstream exhaust pipe 22 being longer than the second upstream exhaust pipe 24 as a result the exhaust system 12 has the potential for generating overlapping and additive noise pulses this potential design problem is avoided by the connector 10 as explained and illustrated further herein with reference to fig2 8 the connector 10 includes first and second external shells 32 and 34 and an internal divider plate 36 all of which are stamp formed from metallic sheet material to define an array of channels and chambers that accommodate the flowing exhaust gas the first external shell 32 is formed.
