Dumpy/dolphin/turn-down muffler. Where to get in USA?

I'm trying to piece together my exhaust system and I'm wanting to get a roto-flo look muffler for the tip. The only problem is, I can't find one anywhere. No muffler shop around here has any ability at all, so I don't trust them to make one for me. All the decent looking ones I find are either in Aus or New Zealand...

This is what I'm looking for:


I'd prefer under $100...

they sell on ebay all the time, or as suggested, if you know how to weld, just get an N1 knock off and weld a turn pipe for it.

I just have a hard time equating the term "dumpy" with anything good...

All I can find on Ebay is the chunk of ****:

http://cgi.ebay.com/ebaymotors/DUMPY...3A1|240%3A1318

Is it possible to order stuff from Aus ebay and have it shipped here relatively cheaply?

Edit: looks like shipping from aus is only about $25 AUS, which looks like only $18 USD at the moment!

I thought about getting the same one but i doubt it will last a couple runs, and will prolly sound tinny. I hate those real tinny exhaust sounds just screams rice but it does look nice if it doesnt sound that bad id buy one.

Nice sounding lobster tail dump tip muffler that works well with rotary = Rotaflo. You get what you pay for, the one he bought looks great and is described as nicely built but unless you're turbo it's most likely going to be extremely loud. Very interested in hearing this once you install!

Rotaflo RF250 = great muffler for NA rotary, even with headers.

This will not be the primary muffler, at least not for long. I too agree it will probably sound like complete ****, so I'm planning on getting a borla xr1 or something similar to go inline with the piping to quiet it down some. I'll let you guys know!

It'll sound great as long as you put something big infront of it where the cats were. borla or magna flow are both great choices.

Has anybody used the racing beat universal inline style mufflers before? They are quite a bit cheaper than the Borla ones, and I figure they are designed specifically to work with a rotary engine. Hyper, don't feel obligated to respond :P

Also I just noticed that muffler I bought is actually stainless steel filled, so that's pretty good for $100 shipped!

I meant their universal pre-silencer, not muffler (too big to fit under the car )
This kind:

I havent used one, but I bet they're very built and will last quite a while. There isn't any different engineering in those mufflers that isn't in anyother preferated core steel wrapped muffler. You can always make your won if you can weld. look up rock wool mufflers. especially on ausrotary.com,
