Here are some pics and a soundclip:
2.25" diameter mandrel bent tubing
My old exhaust 1.75" diameter + crinkle bent
The soundclip is from my digital camera so it doesnt accurately represent the sound at all. The microphone will not pick up such a low loud note. It is much louder in real person.
Now wouldn't it be nice if we could get our rangers to sound like this:
I have noticed a slight increase in power but this exhaust does drone. I am not sure if bassani made these exhaust systems different than the mustang+GTO ones which do have different mufflers or that it is the engine difference with the cats. (The race exhaust above is different than my mine.)
