Some models (e.g. Patrol) and earlier models use a 2-into-1 system, with a single muffler on the right side. The 2-into-2 system uses a crossover ( connecting ) pipe between the two mufflers. Both header pipes and muffler are different for the 2-into-1 system. 1 IMZ Muffler RH, 2-in-2 system, driven sidecar and 2-in-1 system 1 MZ C6 Muffler RH Upswept 1 IMZ Muffler (RH and LH) 2 IMZ Muffler LH, 2-in-2 system 2 IMZ Muffler LH, 2-in-2 system, driven sidecar 2 IMZ C6 Muffler LH, Upswept 3 ' Header pipe LH and RH, 2-in-2 system 3 IMZ Header Pipe RH, 2-in-1 system 3 IMZ C6 Header Pipe RH, Upswept 3 IMZ Header Pipe RH, 2-in-2 system, driven sidecar 3 IMZ Header Pipe for sidecar drive 4 IMZ Header pipe LH, 2-in-1 system 4 IMZ C6 Header Pipe LH, Upswept 4 IMZ Exhaust Pipe LH, 2-in-2 system, driven sidecar 5 IMZ Branch Pipe Upswept Connecting Pipe, 2-in-2 system Connecting Pipe, 2-in-2 system, driven sidecar 6 IMZ Connecting Pipe, Upswept 7 ' Clamp RH 7 IMZ Clamp, 2-in-2 system, driven sidecar 8 ' Clamp LH 9 IMZ Clamp LH or RH 10 6,612,270 Muffler Nut 13 IMZ Heat Protection Sheet Metal RH, upswept 14 IMZ Heat Protection Sheet Metal LH, Upswept 15 IMZ Headerpipe System 2-in-1 system, driven sidecar The Ural 650cc engine had three options; 2-into-2 dual mufflers, 2-into-1 single muffler and the dual muffler upswept system. 40
