FWIW, I've run them on 2 trucks over the last ~8 years. I like them just 'cause they're cheap, and have a little sound. They aren't loud, but when you open up the throttle, you can hear them. it'll never sound like flowmasters, or the newer trucks.
If you mount the mufflers under the cab, you will have a lot of resenation noise, all the time, particularly at interstate speeds. I mount them as far back as I can (just in front of rear axle) usually, and they're OK there.
