Ok i have been stumped at why some other OBS 7.3 have a different sound. Mine has a deeper sound as were the other ones sound alot different, i cant really explain how they sound. I have heard trucks that sound like mine but all of them were 97s and all the other ones that make the different sound were early made 97s and older. Any ideas???

 

intake?

 

Is yours a Cali model?

 

it has a home made intake but my buddys truck is a 97 and it sounds alot different i noticed its the later 97s that sound like mine but the ones made before 06/97 sound different and no its not a cali truck

 

What size exhaust? 5" sounds MUCH deeper than 4" or 3.5"

 

its got a 3in DP to a 4in but the difference in the sound isnt coming from the exhaust, its the motor that sounds different?

 

Cali model trucks are quieter, and so are super duty's.

 

In 97 I belive their was a slight change in injectors, this is a guess Im not 100% positive...
But I know what ya mean Ive heard it to..

 

Its got single shot stage 1s in it and that didnt change the sound very much from the old injectors, it still sounds the same just a little smoother. Im very stumped on why other trucks sound the way they do.

 

You might have a differne hpop, or even the tune alters the idle. A good tuner can really change the pitch of idle.

Afaik, there were no changes to the 97 injectors.
