I had the Timevalve SS put on my 72 4.5 about 2/3 years ago. It has been great, a little louder than stock.

One note is not to use the donut muffler hangers that come with it. Get the diamond shaped ones as used on the R107s, much more durable. The Timevalve came in a little cheaper that the OEM MB system.
