just wondering how it sounds straight piped ? , it is non turbo 7.3L and I want to try it out
, when i straight piped my turbo cummins it sounded sweet but im not sure about the old ford any experience ????

 

My 6.9 turbo sounds bitchin. I had a common rail cummis and strait pipped it and it had a very distinct brrrraaapppp sound and my ford has a good ol v8 rumble. Mine is sidepipe. I'd do it just for the satisfaction of having a noisy *** diesel all the prius drivers hate haha.

 

I have 5" straight back on my 90 F350 7.3 non turbo and its amazing.

 

it will sound too loud and sound like a gasser truck.
