whistling

[lamb3903]

is it normal for my truck to whistle extremely high pitched until it warms up?

What year is it??? What kind of exhaust you got???


Most people are DYIN' to get more whistle - maybe you're just lucky


I have an 07' w/ straight pipe, it whistles pretty good all the time. An 03' will whistle CRAZY loud, that's why alot of guys will switch to an 03' turbo.

i have a 2006 f-250 with a 4 inch straight pipe.

haha when i first read the title i thought hell yea i love my whistle but then again i think the H2E will whistle more. but hm that puzzles me i agree with outlaws questions

I don't know bud.

With the straight pipe you'll hear ALOT more whistle from the turbo (that's normal, and good) Is it something new / different? How long have you had the straight pipe on?

mine's a 95 and it whistle's like a banchee tell it warm's up. Everyone i've talked to says its normal

95 psd 3" down pipe 3 1/5 stright piped

my 95 does the same thing, when i start it up in the cold it whistles really loud then after i drive it a while it stops 3'' dp and 4'' straight pipe....maybe its just cause it so unrestricted???

When i put in my downpipe i noticed there was a butterfly valve after the turbo. Im assuming that closes and holds some heat in the exaust tell the engine warms up.
