Topic: May 1972 Cycle Magazine Honda CB750 Exhaust System Test

Huge thanks to Bryan Woody Wood (not sure if he's a member here). He scanned this and then sent me the link from a Facebook group interaction

I got these pages at a swap meet years ago. It covers (most) of an aftermarket exhaust system shoot out between Dunstall, Triple A, Action Fours, Racecrafters and Jardine. Its missing the last page, but it does have the comparison chart with all the important numbers. Hopefully the images are big enough for you to read the text. Click the image to see it way bigger. The Jardine was the fastest, but also the loudest, Racecrafters came in second in both noise and speed. Triple A however came in third in the speed measures, but was the quietest except for the stock Honda system.

I love this old write ups.  Thanks for posting. I didnt finish reading. Lunch is almost over-back to work. I'll get back to it later.

I had one of the Triple A systems on my 750 back then. It ran great with it on. And such a cool look with the equal length pipes. I finally sold the system to a buddy of mine for his 750 a couple of years later.
