Muffler for a 3.5hp techumesh

[Ferrari motors15]

I have a 3.5hp techumesh engine on my mini bike and my muffler is old, rusted, have holes in it and is very loud. I need to find a new one but I do not have the model number of my engine. My muffler is a bit weird compare to the ones that I can buy on mfgsupply, etc.
So my question is: Do you know where I can buy a curved muffler like the one I have right now?

If the exhaust port is threaded you can buy a muffler at any local hardware or small engine chainsaw store.

My problem is that I can't just put a normal pankake muffler or a cilynder one because my carb is in the way. I need the same stupid desing that I have right now

Can u weld?

If the hole is threaded, you can get whatever you need at the hardware store. Get a 2" pipe nipple, an elbow, and a dinky muffler, and screw it all together so the muffler points to the left.

Yes I can weld, i think I would do like robbie said

Yeah, if you want to do the pipe parts thing, most hardware stores have what you need, aside from the muffler itself. On a 3.5 tec, I'm not sure, most of those small engines will accept 3/4" NPT pipe. Depending on where you want to put the exhaust, you will need one or more nipples, 90*'s, and or 45*'s. You may also need a coupling. With the parts in hand, it'll all become pretty clear. Then just screw on whatever NPT-threaded muffler rubs your buddah. I'd also recommend applying an anti-seize or metallic pipe joint compound to all the male threads before installation, to make future disassembly easier. I can't tell you how many times I've struggled like he// to get a rusted NPT exhaust system apart without damaging the head. It's just steel pipe and cast fittings, the heat rust-welds the stuff pretty seriously...

get the 5 dollar muffler from lowes and then weld it to a nipple or some thing that will fit it so should do you good.

Check with your local lawn mower repair shop, I'll bet they have an offset muffler that will fit nicely. And for the love of god put a chain / clutch guard on it before someone gets hurt.
