Custom parts take time I guess.

Maybe try calling up Elite or Innovative and see if they have some in stock.

I know MPD isn't a huge shop and they do build these to order, but lying about when they will show up is not right... Did they provide a tracking number?

No tracking number. I have to problem waiting on a part just don't lie about it being shipped. I tried to call again but they were closed of course. Have to call in the morning and cancel it. I will try one of those thanks

Well I got my y pipe installed. I got the old one and plan on buying the hd bellows and welding them in as a back up. No more white smoke, gas mileage went up by 7. Throttle response is faster. Sounds great, runs great. Time for the next upgrade. Thanks again for all the help.

I have a 03 6.0 when I start it sounds straight piped like normal when I start driving it goes to a loud whistle and decrease in power doesn't run any codes either anyone had that problem

^this
I had the same problem and I tightened my tube and no more whistle. It wasn't cracked but I guess I didn't tighten it near enough or it wasn't seated fully but definitely check your cooler tubes.

Although check your Y-Pipe as I have read that a torn Y-Pipe can create the whistle.

Hello, everybody can somebody please help me they just bulletproofed my 06 ran fine for like 4 hours and then all of a sudden a loud whine like noise from under the hood defintely think it's turbo related I can hear abnormal noise like air or something at idle it used to not sound that way , and well as soon as I accelerate if the boost preassure rises even a bit it makes loud whine noise no loss of power I was 35 minutes from my house when it started and like I said high speed low speed I can hear it when I accelerate enough to make the boost rise , I made it home didn't force it went very light on the pedal so that it wouldn't make that noise like loud unusual air and a loud abnormal whine , just started all of a sudden any suggestions really appreciated is it possible to be the turbo sticking ?
