Those cheapo ebay turnout's like the OP's and the one I have a simple bent megaphone I'll bet are lighter, and mine cost a whopping $25 IIRC.
Its loud, but like I said, sound isn't a big deal to me. I actually like loud.

Cool.

I thought about the DanMoto more than a few times but I already have a Bassani 4" megaphone which I bought for the brand name expecting higher quality. It has a louvered tube but I can replace it with the 2" perforated or remove altogether.

My can was basically 1/2 the size or less. Quality - yes, quantity - no. LOL.
Mine had a short insert, and I installed it, and some point after a few days noticed - yea, it was gone. Someone must have stolen it. LOL.
Cool.

I don't think anyone can beat the price of the DanMoto.  Yeah, there were issues with the too-big exhaust clamp they had on some & they don't include the bolts to mount their bracket (stock bolts won't work, too long) but the shield fits fine & the can, end cap & baffle look just as good as any other brand I've seen.  The louvered baffle on the Bassani is surprising for such a popular pipe...but I've seen that on others, at least for the cruisers.  They don't seem to be concerned about performance on cruisers.

A good slip-on will have a constant internal diameter throughout the whole length. If not, the exhaust gases expand and slow, then speed up again to squeeze into the the main tube similar to the bulkhead/baffle used in the stock muffler. The Bassani is designed with no jogs so gases maintain a constant flow rate from beginning to end and it's easy to change the louvered tube. The Barons uses a bulkhead, not so easy to make right and way worse than having a louvered tube. I would get the DanMoto for weight savings but not without knowing how it's constructed. One way to check without removing it is to run the end of a tape measure down the tube. If it goes all the way without hooking on a bulkhead, it's good.

Bulkhead?  Explain please  ???  The baffle is 2 1/4" diameter & extends the entire tapered length of the muffler, so it doesn't have any discernable expansion between the headers & the baffle, at least that I can see.  The pipe does have a upward bend so I can't get but so far...but that is getting into the pipe just before the end that slides onto the collector.  It's the same diameter.

I called it a bulkhead for lack of a more descriptive word. You can usually tell by the shape of the exterior at forward end. The DanMoto has a well shape that holds the forward end of the tube just like the 4" Bassani megaphone. The  Barons uses a wall to support the foward end like a canister but with a cone added on.

This is how I want my modded stock can to sound.

That is a seriously deep bass note!  The Danmoto doesn't sound quite as deep but I was quite surprised with how quiet it was idling.  My previous bike was a gen 2 Vmax with a UFO 4-2...it was obnoxious from idle to redline.  At some point I'll pull the baffle out of the Dan moto & see just how much & what it's stuffed with.  Ceramic packing made the tone deeper on an older Vmax that had a Voodoo exhaust with barely any stainless steel in it.
