This setup includes the header pipes, mufflers, upper and lower heat shields, mounting brackets, hardware, and custom polished stainless steel JIS style shield screws with backing and heat absorbing fiber washers. The chrome is in excellent condition.

The HM347 was the factory exhaust used on 1972-1974 CL450 models and will also fit many earlier CL450s.

For full clarity, it fits all CL450s aside from possible slight changes in hanger brackets between models. It first came on the CL450K5 and was also used on the K6, the end of the CL450 run. Using the year as a guide can be misleading in the US because bikes with serial numbers (not true VINs) were titled the year sold, so it's possible that there are more CL450K4s out there than mine which was titled '72 despite it actually being a '71 when I bought it just before September 1, 1972. The title clerk at the Honda shop I worked for when I bought it asked me if I wanted to wait until after September 1 to title it so it would be a '72, and I said yes.

I was requesting additional pictures and any history of this exhaust. I’m well aware of model year changes w/r/t title and year. Thanks and good day, pete

Pete, you might have noticed my remarks were intended for the seller so he might better understand the difference between year and K series on these older bikes, which is important to the entire community and we're always getting new, less familiar members.
