I would select SS unless you going to have it plated.
The difference though is the $40 one does have the spark-arrestor in it. If that's something of concern. I'm super happy with my Autozone parts. $13.68 and easy install.

Yeah I stopped at Autozone, a muffler shop and a local auto parts/machine shop and none could help me.

Prob spent $10 in gas already. If the postman delivers an easy install $40 is cheap. I rarely have a couple hours to run around.

I would have been happy with the first thing I found!

So did you order up that motoGP style from ebay?

When I went to Autozone I found the adapter I thought would work and asked the guy if I could check it for fitment before buying (I road the bike there for this reason). The part specs I gave you fit perfectly and are normally stocked at all Autozones.

Yeah if it don't fit it'll go back Tues.

I was tempted to get a small Supertrapp disc muffler for 1-3/4 in header.

Any left side can with the correct diameter entry will work.

I have three old Style Two Brothers (2004) from 1150GS, very light, very loud. I'll sell 'em cheap. Again.......very loud!

That turned out nice! Happy with the sound? Does it change the sound much as opposed to just the CAT?

And what about the baffle inside, everything seem to be good quality?

It's interesting. The baffle is just a piece of wool held against the pipe with wire mesh. Looks very well made. It came with a nice smooth shiny finish. After an hour ride it's neither shiny nor smooth. No blistering and I can't peel the finish off but it looks more like a new BarBQ grill. It didn't get that hot. Nothing like the cat. The cat still turned water to steam after 5-10 min. but I could touch the pipe with a bare hand.

Sounds same as just the cat with maybe a little more howl if that's possible. Really happy with the performance. No pop on decel. and it seems to spin up quicker than with the huge muffler.

Thanks for the update! I wondered about the black finish longevity. I was thinking I would do chrome if I tried one of these. But I wonder about that finish too. However, the pipe contraption I put together from autozone is still making me very happy. Except for the baffle, it's seems pretty similar. I'm going to see how long I can get away with it.

I too noticed no pop on deceleration. In fact, the only way I get a pop is if I chug it down in at least 3rd. But that would happen with the stock silencer anyway. I think the thing to keep in mind is that the CAT truly does do most of the silencing work and back pressure.

What does that giant OEM muffler really do, drop it 1-2dB?

Yeah, not much. Probably a little more that 1-2 db's in my case, but that's about it. For weekend riding with my group and my daily commuting, I don't need the silencer. If I knew I'd be out on a forestry trail or some place that the less noise pollution the better, I'd switch back to factory for sure. But of course, my factory silencer has a broken part inside of it right now, which is why I did this mod in the first place. I think I may try to open up the silencer and fix it then perhaps rivet it back together. That's for another day :)

The stubby is fine for me for now. If I need more I'll get a Supertrapp 4 stroke universal.
