I love the deep sound of the Super 40s but do they really reduce drone over the originals? Are the Delta Flows too quiet? Any experiences with these mufflers over the original 40s is welcome. Thanks.
On my car the original 40's are the loudest and are the one's I run at the moment and I can run some good number's.I cant run the exhaust out the back either. So if noise is a concern I'd run one of the other's.

I have good luck placing the mufflers just before the diff and run the exhaust out the back. I just use a single crossover pipe.

I just had a Chevelle in the had a Delta 3" ran out the back and its sounded nice and healthy with very little Drown and sounded very nice.
