Thread: 3.9 Twin System

Yea Baby!

should bark nicely around 3,,,,

allow for a bit of LR cam softness and maybe a crackle or two on over-run???

Open road cruise is not too loud , in my opinion.

Being a straight through muffler design, when the foot is buried in the carpet (often ) it is LOUD.

Lots of bark, but not as much crackle on over run as I thought it might have.

The D2 has very good sound insulation,,
am quite tempted now to remove the stock resonator---

Sounds good Jon,

I got a system fitted to my 308 WB that sounded HOT
It was using the original manifolds, but 2 1/4" primary pipes, running parralel back into a twin inlet single outlet hi flow muffler, then 2 1/2" single to the rear, rear section was bent up the same shape as factory WB ute including a 2 1/2" resonator, so looked stock except for the diameter

Sounded like an HDT commodore, sweet, deep resonant note.

Miss that ute

My last 308 ute had twin 2.5 inch with straight through mufflers and no resonators. Balance pipe up the front. Used to rattle windows and set off car alarms...

The ute I am building at the moment is going to be a 355 stroker. Probably have a similar exhaust though .

This is what my County sounded like before the diesel replaced the 4.2 V8 >>>>>>>>>>>> http://www.geocities.com/rijidijau/v8_sound.mp3

And therein lies the problem with diesel conversions...

I could live with the diesel smell, the narrow power band, the good economy, etc, etc.

I just don't know how I would live without the V8 sound!

Maybe when my V8 ute is on the road I can convert my Rangie to diesel, but not before.

If I think about it, every car I have owned for "everyday use" since I was 19 has been a V8 and I am now nearly 35...

I just watched my video again. Two observations.

Nice body movement with the torque of the engine .
How loud is my external fuel pump? It is the whine you can hear towards the end of the video as the engine comes back to idle.
