Last year, my muffler fell off my 2012 Smart Fortwo Passion. The mechanic could not find a replacement for it. He welded on the one that fell off. It did not fall off the car since there was a hitch frame that held just below where it goes. It disconnected again. Is there a place to get a muffler for my 451?

It is noisy and my brother thinks I would get a ticket for it being so noisy. It kind of sounds neat since it has a 'roadster sound'.

I will eventually get another different car, one that one can get parts for (and holds more people and has tires all the same size).

Chances are your flex pipe broke. It can be replaced with an aftermarket one and you will be back in business. The other option is to locate a used muffler and replace the whole thing, or install an aftermarket exhaust.Least expensive would be to replace the flex pipe or find a used (takeoff) system. either way, the hitch will be in the way, you would probably be best off to remove the rear clip to gain access.

Did you do a Google search? There are several online resources. If your mechanic can't find replacement parts, he's not trying. Get a different mechanic.

I will consider it. I am thinking of just getting another car. It was fun driving my 2008 then 2012 cars.

My flexpipe came off a couple weeks ago. I found one I cut a little shorter from Advanced Auto local store of the same width and welded it on the exhaust flange and muffler. Worked great. (though I was alarmed to discover my TIG I use for stick needs service and bought a cheap stick IGBT welder highly rated by buyers for around 100 bucks that works amazing for the money (as other buyers said) to use while I look deeper in my defective welder) I did need to remove with a torch the shield fasteners removing the shield to get to the 2 bolts to disconnect the old flex pipe from the cat and replaced them with stainless steel little bolts. I did notice after doing a search and almost bought after seeing the muffler selling for 360-400 dollars one from Parts Geek that supposedly is a compatible for 124 new and free shipping from eBay. I have no idea how good. Some have reported aftermarket compatible mufflers as louder than stock. There really is not much to the muffler and flex pipe welded to it as a new one is. 124 is quite an understandable price, imo

I’ve seen that listing too, but no picture of the muffler, so I’m hesitant.

Me too when I saw the listing. Exactly what I thought. I looked up the company and called them at an 800 number when I did consider getting one even to have laying around if my weld failed. At first I got someone on the phone that heard the word "eBay" in my first sentence and went off into a rude rant saying, "I can't help you with eBay. CALL EBAY!!!" . I said, "did I ask you a question about ebay!!". Then the rep hung up on me. Slammed the phone down. I called back and I got a women this time who was most helpful. I asked for a pic of the product link if available or a verbal description. The product is listed under the correct part number. Also, the address they gave for the listing is 8 miles away from me and I asked if I could, however unlikely, pick it up. That is impossible because that address was a call center. However, I may still buy one because the product is listed by name for the vehicle with the part number and if it is a 'no-fit' they have to pay to have the item shipped back with a refund. I think perhaps a greater risk may be that the product does not perform as well as the OEM. I remember reading somewhere someone bought an 'aftermarker-non OEM' and said it was louder, most notably, louder at highway speeds. The nice women on the phone said to view the picture type in the part number in Google (but what she meant was other links would have the pic that was not helpful) They did not have a pic.

I will add that I got some minor damage from the flex-pipe failure in that
black lower molding above the tail-pipe. When the flex-pipe failed the muffler pivoted upwardly (and these are known to fail commonly) and the hot tail-pipe melted a circular shape in the bottom of that black molding. Might be a good idea for older Smarts to carry perhaps a small piece of PCV that will go over that tailpipe. I pulled out some paper from the car when it happened but it obviously did not work but improved the condition. If the muffler flex pipe fails you will know it obviously the car will be super-loud. Stop immediately and put that PCV piece or similar idea (PCV will be melted a bit but should hold its shape to insulate the tail pipe heat from damaging the molding) over the tailpipe to prevent that 'melting damage' to the bottom black molding in the rear.
Whatever is used to insulate that pipe will stick there because the tailpipe is pushing upward against the molding

(Now I am working on changing belts. That is a bit tricky. I read someone used a gear-wrench and a piece of 12mm Allen to put in the tension-er. That's what I am using. I am trying that. Can't believe the OEM tool goes usually from 50 to 109 dollars to fit in the tension-er It's just a wrench. Rock Auto had the flex belt that is usually hard to find)

In Europe they are selling aftermarket mufflers for 120 USD. Should be the same - just a simple aftermarket design...
You can find them on ebay.de it is called Smart auspuff.

That is a really simple design! Looks like a plain old Walker muffler with an outlet cut in the side! Heck, you could probably reuse the inlet pipe off of an old one and the hangers if you had a decent welder.
