I need help please. I have an appointment for my truck to go in tomorrow 7-15-2011. I have decided to straight pipe my 2004 f250 6.0L diesel, but after looking at my current exhaust setup I see that my muffler looks like a 6 inch cylinder, and then continues with the 4 inch piping, not oblong like most, so i am thinking that its a glass pack, it currently has a Turbo back 4 inch exhuast sytem. Here's what i need help with... for those of you who have straight piped your trucks with the 6.0L how does it sound, what inch did you use, will it help with anything, or should I just stick with my current aftermarket exhaust setup? I want to make sure that I dont screw anything up, I want my truck to be louder, but if its not going to sound louder than it currently does with the 4 inch system then i wont do the straight pipe, it is pretty loud currently, I just want to rattle windows when I go through town, but not compromise the intergrety or horsepower of the truck or engine. Thanks.

 

the engine is pretty quite till you go wot anyway. my .02

 

What ^^^he said. I have a 4in straight pipe on mine and it dosen't even begin to get noisey till 3k rpm.

 

what does "wot" mean?

 

Yea what they said , mine is calm till you nail it then it s on.

 

Does yours still have a good whistle to it from the turbo?

 

WIDE OPEN THROTTLE

 

Okay thanks, wulfman

 

Read my sig, yes it sounds like a jet

 

Still need to know if anyone thinks its worth it to change or keep my aftermarket exhaust

 

sorry i am new to this website/ forum, so i may be asking a bunch of dumb questions, but what is a "sig"..... signature?

 

Does your 04 have the 03 motor , ICP under turbo 03 , on valve cover 04

 

Have to apologize again, but please tell me what "ICP" means.

 

Yes signature, don't worry you can't ask any dumber questions than i do.
