i have a question i have just put on a 4" turbo back hog exhaust on my dads 04 f350 6.0 and now it sounds like a 747 taking off how do i get rid of the whistle.

You say that like it is a bad thing? That is what most people want, it is the turbo. You could put a bigger muffler or the cat back on if you really want to.

I have put two of the 4" Hog systems on my buddies trucks in the last month. Same thing, Jet fighter, waiting to take off sound. But as soon as the truck is warmed up, the noise pretty much goes away. Exhaust sounds great and really wakes the trucks up. Scotty
