Any recommndations for open header mufflers/noise reducer?

I'm trying to make my ride just a little more quiet than running open headers but without having to get a whole exhaust system. After running open headers for a while I installed the 3'' - 2.5" reducers that came with my new header and to my surprise that did reduce the exhaust noise at idle by a few decibels, however it's still very loud (but cool sounding) when I step on the gas. I found these header mufflers which would be ideal for my application as I'm trying to keep the setup simple without having to use pipes or welding, but I think they are a bit too pricey at over $200.. https://www.summitracing.com/parts/cci-ftd3025c.. . Any other less expensive alternatives? Thanks

If your headers are long tube or mid-length and have a typical 5" to 9" long collector on them look into muffler inserts.
Patriot and Schoenfeld are a couple I know of.

None of this short insert or collector extension type stuff is really going to do much to really muffle the sound for street use.....they exist entirely to fit rules governing tracks that have decibel limits. Those limits are still pretty darn loud, just low enough to take the "bark" out of full open exhaust.

Can't get around the Laws of Physics, about the only inserts that really work are 24-42" long to fit into sidepipes.

Look around at motorcycle baffle inserts. Available in multiple styles and diameters and can be fit in a generic exhaust tip I have taken them and cut one in half for 2 tubes.

Like Eric said they don't help a whole lot but they will take some of that raw bite off the exhaust note.

This shows the muffler case but you get the idea.

This doesn't list the diameter but....
