I need a quieter muffler for my 2021 Toyota Tacoma TRD / Off Road 4WD V6

[IGBT]

The factory muffler is simply too loud and has a horrible droning tone. Can anybody suggest a quiet muffler that mitigates nearly all exhaust noise with out causing emissions and restriction back pressure issues??

Muffler is after all emissions sensors so it will "probably" recalibrate fine and have no emissions issues, but a quieter muffler will tend to cause more backpressure and lose a few HP.

Do you know if it takes the same muffler as the 3.5L otherwise? Being a TRD, does it incorporate a muffler or larger area skid or brush plate under it? If so this may limit the dimensions and pool of potential replacements.

What is the configuration? # of pipes in, # of pipes out, # of mufflers if one-in, one-out for each. Generally that is the first consideration then just what dimensions will fit, and of course the pipe diameter. My point is besides the physical properties to get it to fit and join the pipes, and the baffling for lower noise, a muffler is about as universal a part as it gets and yet, if the non-TRD 3.5L uses a different muffler that may be exactly what you're looking for.

Stock may also be bolted on with a flange but aftermarket could be welded or flange added, even taken off the existing muffler to do so.

I don't know the dimensions vs clearance so suggest you may have best luck posting in a Tacoma centric forum. Both of these seem fairly well populated:

Another option is put in a resonator (mini-muffler) after the stock muffler, again needing the right dimensions and pipe size (though pipe adapters can be welded on too).

All great info...thank a ton. I have much to learn making things quiet.

sometimes a tip that redirects the noise is all you need. Cheap enough to investigate.

For brands, Walker is a popular and “big” brand. I’ve got a Borla straight thru muffler on my truck and does not drone. Borla & Corsa are two “higher end” brands that may be able to help u out.
