Walker SoundFX 17809 - Ram 1500 4.7L
Just a quick video of my 04 Ram 1500 with the 4.7L v8. I replaced the
flowmaster 40 series that rotted off and wanted something quieter. This
muffler has a good low rumble and with the tailpipe it has almost no noise
in the cab. I got the 3" version because that's what I was told I needed
but I think it's 2-3/4" that I need. Oh well, I cut some spare 3" pipe and
slotted it to make a shim of sorts and clamped it down. Tailpipe is a
Magnaflow 15003 universal SS 3". All told I have less than $100 into the Exhaust.
30ft Flamethrower exhaust!

This video compares the sound of two mufflers:
Thrush 24200 - Walker Glasspack Mufflers (old muffler) vs.
Jones Exhaust ATT18S-3 - Jones Full
Boar turbo Tube Muffler (new muffer).
The glasspack has the wobbly camera at night. The turbo tube has the steady camera at dusk.
I tried running the same route with each, with the same driving habits, but
traffic forced me to do otherwise. Sorry about that.
The difference in sound between the two isn't represented well in the
videos. My observation from riding is that both are really too loud. The
glass pack is louder and screams more. The turbo tube is noticeably less loud, with a
throatier tone. Conversation at cruise with the old muff was a shouting
match with many missed words. Conversation with the new one requires just
a strong voice and requires no repeats. Talking during heavy acceleration
with either is a joke.
Powerplant is a stock 1.6L Miata, in a Locost 7 chassis. Stock header into
a 2" pipe. 6" turnout on the driver side, just fore of the rear tire.
