I own 90 5.0 stang and it’s running all stock exhaust in other words to quiet for me so I decided to installed some shorty headers and x pipe cattless...well as soon as I drove out the shop I notice a particular noise I heard before especially on old cars I also have that same noise on my 96 Silverado work truck after the headers were replace as soon I give it gas u can hear it, it almost hears like if it was diesel or when u boiling water, I know it’s not notting major but that noise shouldn’t be there maybe wrong headers or some leaks? What can it be?

I'd be looking at jacking under the house
Take it back to the shop and ask them....Can you take a video of the car and the noise?
It has a cat less exhaust, and now probably with flow master mufflers. If it’s not a rattle as a result of a pipe being too close to the floor, or some other part on the car, The noise you hear is is called “ drone” very typical of that exhaust.
Just speak louder when you’re trying to talk to somebody else in the car, that’s how every other Mustang guy with catless flow master exhaust do it.
