Millipede Monaro (it's a bit leggy!)

Surely a "custom" job from the likes of powerflow would be significantly cheaper than £1200?!
Hopefully, yes. I've heard mention of figures around £800 for custom systems. The thing being a custom system is only as good as the chap bending and welding it up, whereas the Wortec seems to be a known quantity, good fit, nice noise etc.So I'm calling the Wortec "Plan B" for the minute, now just need to see if I can come up with a "Plan A" before the exhaust drops off!!
Yeah I love this thread too, brings joy to my heart that mine may also make it through as many miles as yours has! Thanks for keeping it updated, and good luck with the exhaust - planning the Wortec route for my holey little number too... 6 week lead in though for reference when I checked a month or so ago.
Right, decision made. Millie will be getting a stainless cat-back system custom built.
If lead-time is any sort of indicator of quality then it should be good, the earliest they could fit her in is mid-September!!
[tempt fate]Hopefully the old system can hang together for another couple of months...[/tempt fate]

Also with exhaust why not mod it youwurself to get it a bit louder? 
might be able to bypass backbox or something ^_^
I wrapped the pipes on my v8 m3 and it sounded truly magnificent! couple hours of work with a welder and a grinder. Oh and some heat wrap.
Sorry for OT but how does wrapping the pipes change the sound? might be able to bypass backbox or something ^_^I wrapped the pipes on my v8 m3 and it sounded truly magnificent! couple hours of work with a welder and a grinder. Oh and some heat wrap.
The exhaust runs through the back box and where the pipe runs through it is full of holes which allow the sound out of the pipe and to bounce around the back box.
You can cut this out and replace with a straight pipe, or alternatively I suspect wrap exhaust wrap around it.
The intention being to stop the sound escaping the pipe and bouncing around the back box, and instead to effectively bypass the back box, changing the sound
On topic, how is Millie getting on mileage wise? Bruce hasn't even broken 70,000 miles yet over here, got a long way to go!

Around 228K now, I'm limiting myself to a tank of fuel a month which gets me around 300-330 miles on average, it's the only way I can keep under my insurance mileage!!Means the total is only creeping up slowly though. Might see 230k before the end of the year, especially if the new exhaust sounds good!
). Well just for amusement value, I recorded a clip of the blowing standard exhaust as it currently sounds. I had the phone about five feet from the tailpipes but the noise rather overwhelmed its auto recording level the first couple of times I blipped the throttle so it sounds like a massive misfire when I first rev it and then the level control catches up and it's a bit quiet towards the end. A career as a sound recordist doesn't beckon methinks!

Otherwise, the new gearbox mount arrived so once more under the car on the drive, I look forward to the neck and shoulder ache later
Gearbox supported, gearbox crossmember dropped
I had never spotted what I believe to be the remote clutch bleed mod before. Assuming that's what it is it must have been done when the PO had the clutch changed to the LS7 type.
Old mount off and it's certainly seen better days. For starters the top metal plate should be flat in the middle!!
Old VS new
Right, had a brew, posted this and unknotted shoulders, time to go fit the new mount...

Check your prop centre bearing and guibos while you're under there
Refitting wasn't quite as straightforward as it could have been.
The holes in the cross-member were enlarged and heavily corroded. Not ideal to firmly locate the rubber to the cross-member.
I had a rummage in my spares collection and was chuffed to find a couple of chunky steel sleeves of the same length as the cross-member is thick. Drilled the holes out slightly undersized to the sleeves and pressed them in
Assembled back together with oversize washers to help secure it all. Will check and re-torque in a few hundred miles.
Right, well I did say a new career as a sound recordist doesn't beckon, reckon the same applies to video maker!!
Anyway, grabbed a quick vid on the way home, again the sound isn't great...
Monaro with stainless cat back
My thoughts?
Fit and workmanship look superb, not had a proper crawl underneath but where the factory system had all sorts of restrictive humps and flattened bits to ensure sufficient clearances within the tolerances of mass production, this looks to fit beautifully.
Pipes are just a tad larger than standard without being too OTT I think.
Angled faces and offset of the pipes follows the curve of the rear valance perfectly
In terms of sound, overall I'm happy. There is no droning at all, just a deep growl when applying larger throttle openings. It is surprisingly quiet at idle and when trickling around town on a light throttle.
To be honest they have given me EXACTLY what I asked for - I said it is a relaxed GT type cruiser and I've outgrown all that overly noisy boy-racer stuff. Also we have very good neighbours and I leave rather early some mornings so consideration is due. So yes, overall very happy and it'll be easy to live with and do the occasional long run in.
My inner teenage chav however, is ever so slightly sad at the loss of some of the naughty nascar noises the blown exhaust had been making near the end!!
