Agree with MANU, it sounds like you have an air leak in the exhaust,start it up in the am when its cold and let it warm up for 10 min,then just move the car so you can check the amount of h20 on the floor,mine only leaks by the mufflers. Z

2 puddles of water where the cat delete was done. Has to be the source. Will get redone in a couple weeks, will report back!

That should be your cause right there,any type of codes set?? Best of luck and keep us updated. Z

That seems a bit excessive,while your at the shop would also consider installing new gaskets if not done so already for a secure tight seal, (X2 needed).

Yup got new ones. Also decided to put in a magnaflow resonated X in place of the stock resonator since he is going to have to take it apart and weld anyway.

3500 mile commitment to the "new" setup. Best of luck!

Sound is still there after getting the exhaust fixed. I did some more research and on the EB F150 forums it seems to be more common. Could be linked to VTA.

The SHO has a history of making some weird and odd noises when the bov are vta,from duck to geese sounds,you could always put the front bov back to stock since its the easiest one to reinstall just to hear if the howl noise is somewhat less pronounced at 40mph,best of luck and keep us updated. Z

I would also try to rule out if there is any noise present by the brake booster(check valve)could have a leak contributing to the noise your experiencing,while the car is running try to listen for any hissing sound by the firewall area,the hose highlighted below could have a leak. Z

Take it to a garage with lift, have them fire it up and put in D, give it a gas, and you should be able to follow the noise from under the car. my guess is on a bearing, whether wheel, PTU/differential, or....

Put the blow off valves back to recirculate. Howl still exists. Putting on the winter tires soon, will report back once that happens.

I would keep monitoring for any codes set,sometimes they certainly take a while to appear on these cars. Z

I get a drive train howl similar to gear whine when I first drive my car out of my neighborhood in the morning. Its very faint. I'm guessing its part of the awd system.

sound like it's time to change the PTU/RDU fluid.

I just changed them 10ish k ago. Seems to be between 2k and 1k rpm. I get a kind of piuu sound if it up shifts in that range. I don't hear it anywhere else.
