Put one of those inside of your straight through muffler
Then the alternative is a WALKER 18371 SoundFX which is the OEM muffler for a 91 w250 diesel. 3" in and out but unfortunately it's 25" long and 8.5" diameter.

Sound deader could go a long way to making the cabin more quiet. A friend of mine had a Monte Carlo SS with a worked 383 sbc, headers, and flow masters. I was surprised how quiet that car was.
[SIGPIC][/SIGPIC] 86 Daytona Turbo Z C/S with a full 89 Shelby swap, back on the road and soon to be painted (and lose that Oggie Fisher black) 83 Porsche 944, 5 speed, all stock. 2014 Toyota Tacoma 4x4, 5 speed, daily driver. 2017 Trek 1.2 bicycle.
So, After talking to Harry last night, the problem isn't necessarily the muffler. I think it has a lot to do with the lack of sound deadening inside the car. The car has a layer of heat shield (foil type) and then a plain carpet (without the jute/felt) backing. None of my cars drone, even the one that exits out the side.

Solution found.
Installed MagnaFlow 12219 and MagnaFlow 11249 with a pipe straight clear out to the bumper.
Exhaust is now super quiet and doesn't drone.
Nice, good info

Would love to see a video to hear the result
The electric car idea would work. I've seen Teslas running in the 11's at 115mph. A P90d with ludicrous mode should do it.

Fair enough. I'd love to hear the car in person some day, do you keep it in AZ, or do you have any plans to bring it to any events outside of your locality? Was in AZ years ago, delivered (drove) a 72 Plymouth Scamp from Youngstown, OH to Phoenix.
Do you have any pics of how you installed them? Or maybe a description. I'm with you on the Omni being too loud. I'd also like to quiet down my Omni. The straight through bullet muffler is very inadequate.
Dynomax VT - spring loaded butterfly with off center pivot so it pivots easily; I've got one on my Spirit R/T TIII, no drone, power improved.
I tried to post a link but I got the "forbidden" problem
