Installed Spartan, now exhaust sounds like blow torch

[tictactowing]

Is that normal? I am running the 275 tune, with AFE stage 2 intake, and cat/dpf delete exhaust.

I tuned my 6.0 before I did my cat delete. But when I deleted my cat you can hear that turbo for sure. When you first start the truck you should hear the motor running. Then a few seconds after you should hear that hair dryer sound of the turbo spinning

[amb82]

haha. Yep totally normal. The pissed of hair dryer sound is just the turbos you here. You let her breathe

[blackcloud2k]

normal and a good sound to me. People always look at me weird when I am fueling up and it starts whistling.

6.4 sounds a lot different than the 6.0

6.4 is an odd sounding diesel because of the turbo setup, but I like it because it is different.

[blackcloud2k]

I love the sound of a 5" straight piped 6.0. They sound MEAN! best sound in my opinion, but I love the 6.4 sound to.

[TheFordman87]

I like the 6.4 how the motor itself isn't as loud. But I love my 6.0 plus I have a KR so it's really not loud at all in the cab

[srjd]

The 6.4 you can hear the turbo right away it's on the 6.0 that there's a delay when starting

[TheFordman87]

Yeah I like how it delays when I start it up I tell people listen and when the turbo spools up they are like what is that. I'm like I flipped the switch and turned my jet engine on. lol
