Exhaust: Cocktail Shaker vs Dunstall

[High On Octane]

Hey everyone. If you've been following my '58 Indian build, I recently built a 2-1 exhaust out of my dual exhaust. I previously had a pair of EMGO cocktail shakers on the bike and really liked them so I was just going to go with a single. But I was just offered a brand new EMGO Dunstall replica for free so I'm going to throw that on there now. I was curious if others have a preference for either of these vs the other? Does the Dunstall have any flow restrictions from the 6 hole outlet? From the videos I have heard of the Dunstall, it has a nice throaty tone. The donor said he even packed the baffle with fiberglass already but ended up selling his bike before he installed it. My thought is to get a 1.75" 45* adapter and mount it up at an angle. Here's what the exhaust looks like now, except it has been wrapped in black header wrap.

I like the Dunstall. I've had them on bikes since my '71 Norton in 1972. I have them on my T140 now.

The Emgo copy is not the same but close. The Dunstall had a washer welded in the perforated tube where the Emgo has a perforated disk. Minor detail and the disk can be drilled or removed. This is the only restriction to flow and is minor. The small tube bundle at the end is to stop the 'nightstick' test for straight through exhaust.

Your buddy will confirm that the Dunstall is difficult to pack and the glass wool blows out quickly. The last time I packed mine I used SS pot scrubbing pads around the tube and wrapped with tape. As the tube was inserted into the body I used a screw driver to force extra tuffs of the steel wool into the body for more sound damping.
