Default Engine masters

Did anyone see the Engine Masters about exhaust and how much power different mufflers killed? I have to find the balance between good sound and being able to hear the radio or have a conversation. Anybody got any 3 inch exhaust sound clips? I can’t have drone either as I will drive it almost daily

Here is a video from my 73 before I put it back to stock and sold it. Motor is the same 600hp currently in my 68.

Exhaust is 1.75" headers into 3" mid pipe with X into 3" Ulttaflow headers (19" long case) and out 2.5" tail pipes. Windows are open.

That sounds good. Ultra flow mufflers?

Yes ultra flow mufflers, not headers

If you want to hear your radio and have headers and 3in I would not go smaller than 18in!Tom
