I have a Jensen Interceptor. 440 2x4bbl with a 270H comp cam. 9.5 to 1.
I put on Delta S&S headers which are like a block hugger header with a longer collector and slightly longer primaries.
I made my own 2 1/2" mandrel bent exhaust straight out the rear, no crossover.
I have very large Walker mufflers each side in the original muffler hangers. 2 1/2" in and 2 1/2" out.
I built 2 1/2" Dynomax Bullets into my exhaust tips.

I love the sound of the car. It's very loud bass tone honestly. It's not quiet. But I love the exhaust note - would love it if any of my other MoPars had the same sound. Maybe a touch of drone at certain speeds and rpms but it's the exact sound I like. And I've owned quite a few performance 440s.....
