Single or Twin system

[HZSandman]

Will have to measure for you agro.

Here's where mine used to come out, level with the bottom of the mudflaps (and yes they have been taken off as well).

Twin 2.5" running through extractors and hooker aero mufflers with no equaliser tube. I think is sounds awesome!, my mates reckon they can hear me coming a mile off:shifty:!!!!!

I had a single exhaust on a V8 i had a while back, just sounded too restricted. (Though that could have been because it was a 351C....)

It was going to get murals on each side (one side have mask on, the other side with mask off), and yes that was the reason i took it off the tailgate.

Now it will get Sandman stripes in the correct colours.Will look good when both my vans travel together. :D

Twin 2 inch on mine. No balance pipe. Mine come straight out the back. Love the sound, and definately love the look.:D

G'day

My 3 Holden have twin system, the 2 twin system I got put on (Maloo and the HZ ute) and the other came with a twin system, but it quieter (HX van). I grew up with twin system on V8, i think it great music to the ear.

I have the same set up as jbsandman76, in regards twin (unsure what pipe size i got put on, I thought 2-1/4?????).
I also have sport mufflers on, which make it sound sweet.
Hx van, I'm going to have it change, the mufflers, she abit quieter and I like the long chrome tips look.

I know this is an old thread and slightly off topic, but was the standard HJ/HZ exhaust a single or twin?
If so what sizes where they??

You could order them with factory dual exhaust which was 2"...I think from memory. Most of the vans i saw back when I worked in spares at a GMH dealer came with a single exhaust though and dual were fitted aftermarket.

I think I am repeating but our original red van was single, and still was when we bought it, we have changed it to dual though.... and the GMH guys told us what GTS said as well

The twin system must have been an expensive option in the day.
