Exhaust too loud

[peperino]

Hi gentlemen, hope you are having a great time!

Today I wanted to ask you if you know a cheap way to make the exhaust quieter. The Triax 250 (as it's known here in Argentina) has a unrestricted, loud exhaust. It gets tiresome after long rides.

I've been talking with some mechanic and they say they can make a custom, quieter exhaust. And expensive. So I'm looking for a cheaper, easier solution.

Here's what it looks like inside. I wonder if the USA version has something else to make it quieter that this one doesn't.

A lot of the noise of the RX-3 comes from the air box, not just the exhaust....

But a Supertrapp muffler is tuneable, so you could fit one of those to it.....or cheaper to buy some ear plugs

You should be able to buy a universal muffler insert which will quiet the exhaust. I am unfamiliar with the current models, but you can probably find one if you search the internet.

When I took the test on a greeves 250 wearing an expansion chamber I stuffed it with course steel wool. Was about the last year off-road bikes came with titles around 1968. Ran like crap and after tested it blew out!

Unfortunately here we don't have many choices as ebay, etc. Also, people here tend to do the opposite, make MORE noise. :(

Would someone be so kind of taking a picture just like the one I took in my OP so I can compare what's the difference between the model sold in usa and argentina? Maybe with that picture I can ask a mechanic for a cheaper alternative.

Thank you

You can reduce exhaust noise by inserting a pipe of smaller diameter into the muffler outlet. I suggest you measure the inside diameter of the muffler outlet. You can then insert a piece of copper pipe, et cetera, which is smaller in diameter, and bolt, or screw it in place. The smaller pipe will definitely reduce the exhaust noise.

Please post more photographs of your muffler, and your entire exhaust system.

That would be great. And if one could do it with cheap stuff from a hardware store, would be fantastic.

Here are some more pics of the exhaust. If you have the time, please show me yours.

Try removing the end cap, you may find that you can stuff more insulation in the baffle.

So, remove rivets, check for room for more packing material, if so stuff some more, replace rivets, try ?

You're welcome.

I looked at your photographs. You have the same exhaust system we have in the United States. I'm sure you can reduce exhaust noise by following the advice I posted earlier.

If you drill out the rivets, you can remove the end cap of the muffler. Then you will be able to insert, and fasten, a smaller diameter pipe in the muffler outlet. Finally, you can replace the end cap, and install new rivets.

Awesome. It is the same? It is clearly making more noise than the one I hear in this video at the 2 min mark.



I'll can try the pipe thing. Is there something I could look for on a hardware store?

Yes, your exhaust system is exactly the same as mine. The bike in that video has a different exhaust header, which was later changed.

Measure the inside diameter of the muffler outlet. Then search the hardware store for a smaller pipe, made of any metal, which will fit inside.

Alright.
I'll record a video of mine tomorrow so you can hear it. I'm pretty sure it sounds louder than the one in the video.

Thanks !!!

Of my 3 street legal motorcycles, the exhaust on the RX-3 is the loudest, butI don't consider it excessively loud(and I am NOT a fan of loud bikes), but it IS louder than either my XT250, or my NC700X (The NC is crazy quite! )

I guess my hearing is compromised. The exhaust sounds just right to me.
