New exhaust, jet sounds?

[NWPowerstroke6.0]

I just put on the 4" MBRP kit with cat and muffler delete (very easy, took 2 hours tops) and i was expecting allot more sound out of it however it doesnt get much louder until i get to about 2000 RPMs which i read was normal. However when i first start it if i walk around to the tailpipe it almost sounds like a mix between a jet and exhaust brake. Checked for leaks at clamps nothings leaking its all out of the tailpipe. I dont have an exhaust break. Once its warmed up its a little less but still screams at idle. I have the SCT X3 with factory performace programmed as of now. Is this normal? I'm thinking just a pararnoia question but i wanted to be sure. This is my first diesel and new exhaust experience. btw those of you who were considering it i would recommend it. takes away allot of turbo lag. Thanks!

Welcome to Powerstroke.org!!!The jet sound is normal after a kitty/muff delete.

Normal.


What year is your truck?

Straight piped 6.0 sounds about right

[pizza pig]

yup normal, its due to your VGT (variable geometry turbo)

perfect thanks exactly what i wanted to know. and its a 2004, i just bought it a 3 weeks ago from a dealership here. the second day i had it the tranny actually went out on me (6 speed) going to work in the morning. it took them 2 and a half weeks to get it back to me. the replaced it with a brand new one which was nice.5700 i didnt have to spend! i thought that was kind of early for only 92000 miles

If it's early '04 then you have a '03 turbo.
