the system on the right is a stock SE exhaust. the resonator is that big can at the very end with the tip. the system on the left is the stock R/T 6-speed exhaust. it is different than the auto system.
also, the 6-speed exhaust uses 2 1/2" tubing and a H-pipe while the auto system uses 2 1/4" tubing and a X-pipe. the auto system uses that huge suitcase muffler. it is needed because of the MDS. when the engine drops 4 cylinders, the sound completely changes. the suitcase muffler is designed special to be really two systems into one case.
