Ordered and received a CB Extreme muffler for my 1994 Toyota 4x4 w/22RE which looked the same as all the other mufflers in this style such as Flowmaster and Thrush throughout the ages without the higher costs. Once welded in place and running through a stock 1 1/2 inch exhaust system, the audio tone was very noticeable and very reassuring compared to the turbo muffler it replaced. Although my 22RE 4-cyl. quiet at idle, it now produces a stronger, more powerful growl (really lol!, no nasty bee buzzing or gurgling noise like double glazing) at higher rpm through the gearbox.
