this muffler sounds awsmome on my 66 cadillac, nice rumble at an idle, music to my ears during smokey old tire burnouts.

I installed this by removing everything from the stock muffler back. Installed the series 40 exactly where the original muffler was and had exit pipe turn out just in front of the rear tire. Unless you were in the throttle really hard, you couldnt tell if it was a V8 or the V6.
