Designation | Nature and reason for modification | Production breakpoint | Op. no. |
Exhaust shield | Model 201: Shield enlarged, from right firewall side up to forked frame member (2nd version). Heat radiated to forked frame member reduced. | 04/83 | 49-100 |
Exhaust shield | Model 201: Shield enlarged, from right firewall side to beyond the forked frame member (3rd version). Heat radiated to forked frame member reduced. | 03/84 | 49-100 |
Final silencer | Model 201: Connecting web between final silencer and tail pipe to prevent vibration fractures. | 06/83 | 49-100 |
Center silencer | Model 201: Supporting sleeve press-fitted into center silencer pipe outlet to increase stiffness. | 08/83 | 49-100 |

Designation | Nature and reason for modification | Production breakpoint | Op. no. |
Front exhaust pipes | Model 201: Connection to exhaust manifold as tulip design (improves sealing). | 10/84 | 49-100 |
Front exhaust system | Model 201: Two 4 mm holes are fitted 180° offset from the vertical (ahead of firewall) at outer pipe of double-walled front exhaust pipes. Prevents cross-section constriction as a result of gas expansion. | 11/85 | |
Exhaust system | Model 124, 201 with engines 102.96/98 KAT: Pre-catalytic converters and hole for oxygen sensor no longer fitted. | 09/89 | |
Model 201 with engines 102.962/985 KAT: Engine output uprated by 3 kW as a result of modified exhaust system. | 12/90 | ||
