I have a 1996 1-ton dooley and I bought a 4 inch diamond eye exhaust for it from the the turbo back.

I don't really like the sound of it, anyone think I should just take the muffler out and sraight pipe it? anyone have theirs straight piped?



Thanks

 

there not going be diff in the sound

the muffler is just like straight pipe

i have the same exhaust all i did put muffler on backwards

 

mines straight piped with no cat an no muffler sounds nasty

 

Cummins got hole diff sound then 6.5 do

 

Do it. 6.5 sounds awesome straight piped. I had 3" straight with 4" tip. An un crinkled x over makes a sound difference too.

Sounds like a bbc wound out and a diesel at idle.

i got a dyno max resonater with my diamondeye which is pretty close to straight and its not super loud. sounds nice.

 

mine has a 3 inch straight pipe, its loud when i want it to be but its fairly quiet cruising down the road. straight pipes sound good on all diesels IMO

 

I have a 94 Dually low rider 6.5 with straight back no muffler.

That thing sounds nice, your hear the turbo nicely and it has a deep and clappy sound.
I love driving through street with buildings close to the street echoing back at me.

But its not so loud that it bothers you in the cab. But mines a dually and kinda hides the pipe behind the big fender and tires back there, so it might be louder in the cab if yours isn't a dually.

I would get rid of the muffler and if not done already, get a down pipe thats not smashed all to hell like the stock one. Get a 3 to 4 inch round down pipe and it will improve power too.

 

i straightpiped mine and i love it i had my homemade tm turned up and when i left work from straightpiping my truck i looked at my boost gauge and it was sittin on about 20 to 22 psi

 

you will be buying new headgaskets soon or worse a block if you keep it up that high
