May 1972 Cycle Magazine Honda CB750 Exhaust System Test
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 swear that they installed the Triple A system wrong, like the pipes were put to the wrong cylinders…

I have a Triple A pipe, and I have seen 1 other one installed. It is seriously wacky. I love the look of it, plus it really works well without making a ton of noise. I wish I could find a NOS one.
