6.4 sound...

[Bigaustin57]

Has anyone figured out how to get rid of the "vacuum" sound the 6.4's make? and is there something i can do to make my truck whistle loud?

Get a muffler and a single turbo

[clutchdabomb22]

air intake for the whistle, 5 in turbo back with muffler gets rid of the hair dryer noise.

wait for that single turbo setup to come out lol

I am in the process of finding out with my big ole muffler/exhaust project.

5" turbo back meaning downpipe? Where do I get this.

There isn't a 5" turbo back system for the 6.4L. Only a 4" downpipe in to a 5" downpipe back. Some people are mistaken about what they have on their own trucks.

I would recommend the Magnaflow muffler. I have heard one truck with it and that was all I needed to hear to confirm it sounds great. Truck has a 4" downpipe in to a 5" downpipe back exhaust with a 5" Magnaflow muffler.
