Smithy's, a blast from the past

February 28, 2012
Mufflers come and mufflers go, but Smithy's glasspacks have been around for a couple of generations. They're simple, well-made, and they do a good job of reducing restriction in the exhaust system--free horsepower if there is such a thing. The tone also can't be beat--emphatic but not harsh. I have been using 26" Smithy's for several years now and recently ordered a pair of the 30" to use when I modify the exhaust this summer--the variety of lengths available gives the option of getting any sound level you want.
Pros:
  • Mellow sound
  • Low back pressure
Yes, I recommend this product.

these sound amazing, seriously like music. if you are looking for a serious sound, without the pop and crackle and harshness of most glasspacks, choose these, just a nice deep rumble.

  • Sound

how much quieter are 30" smithy's then 22" smithy;s? I am changing the exhaust on my 51 Ford with a Flathead. I would still like to hear the radio and talk in the car. I now have cherry bomb on it and they have rusted out. Time to change

Unfortunately the manufacturer does not list decibel ranges on the different mufflers and it depends greatly on the engine size and output. On a flathead application the 30” would give some sound reduction over the 22” and if hunting for the quietest the 30” would be suggested.
