Got a bit of a start on the dump. Cut the taper to fit the v-band, ground it perfectly flat (one of the (multitude) of keys to a half decent tig weld I slowly discovered doing the rest of the exhaust...) then tacked them together. Measured up the first bend off the taper and cut the end off the 90 degree bend. Because of the front mount manifold it means the turbo is on an angle so you need to go down and away from the engine at the same time. Makes it a bit trickier...

I'll be cutting more off the end part way through the 90 but tacked it on and I'll work out where to cut it while it's in place.

Ha ha!! You’re persistent!

I currently have one point left on my licence so I’ll be looking for ways to be less obvious to inspector Po Po. I don’t think a bonnet exit exhaust and screamer will help me achieve my goals ??

Got a bit more done of the dump. Pretty much out the bottom now. 

Has anyone come up with a solution for the a/c evapirator drain pipe? Ive gone closer to the firewall than standard. Might just chop most of it off and leave a little dick poking out. 

Did my first full (not just tacking) weld on the dump pipe. Did a terrible job ?.  The rest of the exhaust I didn't use filler. With the dump I did so felt a bit uncomfortable. I get so bloody nervous and jumpy when im welding.  I need to chill out and slow the f down!! Once it's ceramic coated it won't be so obvious how nasty it is. 

Slow going but good to be making some decent progress!

The only restriction in mine is the dags from my cocky shit welds! ?

I'm a bit scared with how loud it will be with just a rear muffler. May have to put a resonator in it at some point. 

Thanks mate. I probably put a bit too much pressure on myself for a bloke who learnt to TIG off YouTube!

The sense of satisfaction at the end of this bloody long winded exercise from having done everything myself on this car will quickly overcome my self disappointment over a few shoddy welds!

Just have to keep pushing while the motivation bus is in town!

I’m up in Sydney for 3 days at the moment so missing a few nights in the shed after work because of that.  Hopefully got a few full days at the end of the week to finish off the exhaust. 

A few more bits and pieces done. 

I seem to be 2 steps forward one step back. I keep adding and changing stuff as I go...

The dump pipe was getting too long to feed down through the engine bay so I've added an extra v band in to make removal easier.

Got a few more sections of the exhaust done today.  The dump is almost connected to the cat which is he original part of the exhaust I made when it was still going to be twins.

Went and got a few sections of 3” stainless bead rolled to be used for the compressor side to intercooler and then on to the intake.

Had the compressor housing hose section machined off to allow fitment of a v band rather than a hose. Need to order in the 90 degree bend though as it’s some sort of weird v band size...

Got a start on the wastegate merge into the exhaust. Wow, that was a shit of a job cutting the pipe to fit the exhaust nicely. I just couldn’t get it perfect. With TIG you don’t get too many chances with crappy joins. Decided to just go with it and try to panel beat it into submission! God I wish I had a pipe notcher after that.....  Would have made it so much easier than all the cutting and grinding I did on it.  Took me  Hoooooouuuuurrrrrsssss!!  Started tigging it up using heaps of filler wire to bridge the shonky gaps!

Still a fair bit to do. Waiting on another flex joint (baffle style) as I wasn’t happy with the one I already had. It was way too big. It’s supposed to be 4” but the 4” tube was dick in a bucket. Way too big to be able to TIG. Even MIG would struggle to bridge the gap it was that far off.

Pretty much finished off the wastegate merge. Man what a mission I made that into.... I reckon i put 5 or 6 hours into that section alone ?  

Lucky I'm enjoying it! Such a sense of achievement each time I finish each section.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
