Remember the idea is that more bark would be a lower number.

Massaged the list a bit. Reorganized is more like it. I'm guessing that any of the pipes without any baffles at all would be similarly loud. Just on the loudness scale they may all be the same volume. Where there could be a difference is in the tone. Certainly unbaffled fishtails are more rappy than thunder-y.

Um, ok ???

Nevertheless, the sound quality of Bubs is certainly far better than TORs. They should be at least a 7, if not an 8 (I know the SS crowd won't like that...lol).

I can still remember odatbob complimenting me on the sound of my Bubs, on a ride from Issaquah back to Renton. He had TORs on his 07 TBA.

Interesting, I bought my Specialty Spares because I thought they had a very "throaty" sound. The only others I've been able to compare to besides stock are Bubs and TORs. I like the sound of my pipes with new re-packed baffle material the best. As the baffles age they do get more raspy at high rpms. New baffles reduce the volume a bit but don't hurt the low end growl.

Great pipes. I hope Dale gets the company going again. Mine are 6 years old with 22,000 miles on them and still look like new. I order Moose fiberglass 4-stroke muffler packing to re-pack them.

I think you're still missing the point. It's not a competition. Higher numbers aren't better, just different. I think I'm going to have to change the number scale to a more descriptive continuum, like "rappy, growly, neither rappy nor deep, mellow tone, deep tone, thunderous." I need a damned thesaurus...

I like Bubs, too. Almost got some after riding behind AmyLee. Then I heard Zdenko's Specialty Spares and liked them better. Doesn't mean SS is better than Bub. Just means my subjective preference is for SS. If I somehow lose both of my sets of SS pipes there's a good chance I'd buy Bubs now that SS is out of business.

I rode with a member here once and he had BUBs, great sound but too tame for me.

Good meaasure of where I sit, so to speak with pipes.

I wonder if there are different TORs though. I have long slash cut TORs for my EFI Speedmaster that seem quite loud. They are straight through with baffles around the circumference. The way the TORS are referred to, you'd think they were relatively quiet. I beg to differ, even with custom earplugs they are more than loud enough.

I'd love to know how these pipes measure up with the new impending SAE J2825 tests that will be coming to some jurisdictions.

Indeed there are, I have two set's of long slash TOR's. One on a 2003 America, one on a 2004 Speedmaster.They look identical but the Speedmaster is much louder and throatier.

Mine aren't on the list unless you add "short TORs, gutted, 6" cut off and wrapped with stainless tips" but I would rate the loudness as "UnGodly" or possibly "Genuinely Painful On Trips Of 20 Minutes Or More Without Ear Protection Causing My Ears To Ring For About 2 Hours" but you can edit that last bit down.

Yah, I'm taking them off the bike. These are just WAY too loud for my wife and I, even with custom fitted earplugs. Just did a 2000 km trip and at the end of a 700 km day our ears were ringing. I like my hearing.

Thanks,
H.

I'm going to go with the "unbaffled anything" category here.
