Chevrolet Silverado 4.3 walker muffler
This is a stock single 2 3/4 exaust pipe with catalytic converter delete
and a cheap walker soundfx muffler.
I'm happy with it, 55$ and it just quiet enough. Sadly I can't say what did
what as far as sounds goes since I removed the (internally shattered)
catalatic converter at the same time.
It sounds better than stock but I don't know if it's louder because the
cat is no longer there or if it's the muffler that's louder.

1989 Caprice Classic Wagon exhaust sound
My '89 Caprice Classic wagon (w/ Olds 307) restoration project. At least
the Exhaust system is brand new. Yeah,
I know the engine is not running very smooth when cold, stalling when
letting of the gas (like in this video) and that the spare wheel well is
rusted out. Like I said, the car is a restoration project, slowly
improving. At least the Exhaust system
is brand new, as the old one was nothing but holes and rust. One Walker
SoundFX muffler, no catalytic converter as it was rusted out, not working
and is not required here in Norway on a car that old. Actually, the car
passed the bi-annual inspection yesterday. ;)
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 $100 into the Exhaust.
Dynomax Ultra Flo vs Walker Muffler Comparison - sound levels and sounds!
We've compared two mufflers in search of quiet(er) performance.
*EDIT* Dyno results
are in! 443 rwhp and 490 rwtq. Taking into account the 1.5 degrees of
timing we added, the mufflers cost NO power. Before we made 422 rwhp and
EDIT EDIT: Car has run a best of 10.77 @ 128 so far... still some left in
EDIT EDIT EDIT: The car turned a 10.55 @ 129.3 and the block and trans let
go. A Dart 363 and a built Powerglide are going in!
1998 Chevy Prizm LSi with Walker Sound FX Muffler
This muffler costs 78.99$ plus whatever tax at Autozone. It has a nice deep
tone sound and OEM standards. Great buy compared to the 140$ Walker Quiet
Flow muffler. I put this on myself about a month ago in the freezing cold.
