MUFFLER SET T100 1959-73 EMGO TAIWAN (Replaces 70-4157 70-4158)
Left and right muffler set for the T100, Emgo reproduction replacing older factory numbers 70-4157/70-4158.
This is a muffler set for the T100, sold as a matched left and right pair under part number 71-2017/18T. The catalog record lists it as an Emgo reproduction made in Taiwan, and it replaces the older factory numbers 70-4157 and 70-4158, so if your parts book still shows those digits, this is the current equivalent.

Mufflers bolt onto the tail end of the exhaust header pipes and quiet down the exhaust note while directing spent gases out past the rear of the bike. Since this is sold as a set, you get both sides at once rather than sourcing them separately.
The catalog ties this set to the T100 across a 1959-73 span, but beyond that we don't have more detail on hand. Give the shop a call if you want to confirm it matches your specific setup before ordering.
