hooker aerochamber's anyone?
I have them currently on my '79 Magnum. The engine is a '78, 400 with headman eliete headers w/2-1/2 inch pipe, "H" piped, pipes run to the bumper.
I don't have a sound clip, but I could in a day or so if your interested in hearing this low comp engines rumble. They do have a different sound than most other mufflers. And like said above, there preety decent on the noise level on the inside.
