Turbo back exhaust? Update!
 

Any recomendation for size, assuming your running the stock turbo? I was thinking 2.5" would be big enough, and would sound nice. Most all the aftermarket Ford/Dodge/GM diesel trucks run 4" as the standard aftermarket size for an upgrade. All those engines are more than double the displacement of the D24, it would seem to me that 2.5 would be plenty. Is that even a waste of time? Is it worth even building a bigger exhaust? I would straight pipe it no matter what, as I love the sound. Dumping the muffler should help it flow much better and drop EGTs I'm expecting.

Yes, 2.5" should b enough, in the gas volvos is usual is 2.5" to 3" exhaust systems.

years ago, I seen this "IPD'ed" '83 760 Turbo Diesel sedan. It was Silver with black accents... It just had a 2.5 straight through exhaust routed just the same as stock. And It sounded so freaking good. I don't know what happened to that diesel though... I really like it. Also had IPD sway bars on it. Manual trans. Converted to Bio diesel. And it was pretty powerful. never seen a rebuild either.

What do you have for exhaust on your car?

Jason

Stock D24T downpipe, then ballooned to 3" piping to side exit. No glass pack no mufflers, Just pipe.

Just run a 3" back from the turbo maybe one muffler or resonator.

Without having to custom make a exhaust, does anyone know who sells 3" exhaust for the 700 turbos?

Jason, how does your car sound without the muffler? Not loud. I guess I could just un bolt mine and find out.

It sounds freakin' great! Kinda like a little cummins. I have it steped up to 2.5" before the axle, then to a small piece of 3" then a 5" chrome tip to dump out the soot. The bigger you go, the deeper it is. I will do 2.5" turbo back once I have a different turbo. I'll have to post up some video.

I made a 3 inch system with one muffler its 3 inch all the way from the turbo, would like to get a bending tool so i could do it a little bit more proffessional...
Sounds great and you could really hear the turbo spooling....
My wife hates my car :-))
