Thank you. New muffler is great. I can hear the engine on the highway, but not annoying or a "drone". Growls good at full throttle. Mello below that. I think it is well worth the investment. We will see how it holds up long term.
I am not on the '67-'72 chevy truck forum. I did have a 1970 3 door Suburban that pulled my car to the races every weekend for three years. Great rig. Told my wife to never let me sell it. After I bought the Avalanche, guess what happened? Yup, sold it
All my 70-72 parts went away with the suburban.
