The real 273 HP exhaust sound

thanks, I'll check that out. I don't have this fish home yet so I'm not sure what I will do. My other one was a /6 so it was more simple. In the late 60's early 70's I was into Mustangs. Had a boss 302 then a boss 429. Bought them new and they came with duals so I thought that was the way to go. Now I have seen the light and love the early model fish.
