Ok, so part 3 we've done pretty much all of the cat back exhaust now
or the turbo back exhaust we just got this rear tail pipe section to
me now with the 8-inch body silencer.
It's dropped the centre of the exhaust quite far down but still not
far down enough that we're away body seam this is always a bit of a
problem on the Astra H with a 3-inch system.
You don't really have enough room with body seems that banging between
were silent will go in the bumper and it stops you from having the
exhaust booked up as high as you like so we're going to have to come
around here with a 90 degree bend but also have to drop it down at the
same time.
So we can have that kind of come out of the silencer drop it down so
we can come away from this body saying and then round as a 90 degree
bend and then background again and then what is coming just point it
up, so I'm actually going to do this from titanium.
So I can't have no idea for a little while.
Love you lots of Instagram inspiration and really cool kind of striped
titanium intake so we're going to attempt to do is call the titanium
pie quartz hackamore together cleaning material spotlight.
and that actually change the colour of the
the surface of the material before we weld it and then we weld it will
get those kind of golden or straw coloured titanium stripes around
each well joint, so hopefully all pretty well.
We'll see you will see how we go worst case scenario.
We just brush it off and the whole thing up already had a bit of an
idea of what I can do with our off-the-shelf stainless steel pipe.
That's why no one deeper cuts going out there one decent one radiator
works fine because we've got quite a lot of room the back.
He will go for quite a big sense like a 1.5 d centerline radius and
that just gives it a bit more sweeping.
Look at the back not 100.
What will do for the tip yet might just go for a 4inch tip just a
straight cut tip something like that as we get there.
Right, so I've packed up the one-and-a-half divan, so we're going to
use for the tailpipe.
So that is pretty much going to sit there something like that.
So got to get some kind of tip in there now.
We just need to work out.
How long is a piece of straight we need and then what we need to get
up there, so we're not going to work.
Obviously not gonna be able to fit in a normal night agreed because
I've got to step down past this this body seem so I think having
already protect it with stainless stuff.
Just take it together I can see if I do that 7pi cuts.
At the 1D radius little hours to step down and Away still get a full
90 degree bend so yeah, really.
Right, so got this other piece stacked up now this this kind of 90
degree bend which is stepped around on me now put on the car.
We got like a fool knighted reverb.
It's got an extra power cut in it, so normally would be 667 a 12:30
7/2 degrees to 90 degrees, but we got an extra one in here and that's
steps down.
Sorry, put that there you can see it's it's cooling down and away from
that body scene.
Getting the exhaust to a nice height that it can run along and then
back up again and out the tip so next time we need to do it's got a
piece that's going to pop into the silencer there, so I've got a 45mm
deep swage in there, so I'll probably 50mm piece and I forgot that in
there.
We can hold up the other 90 degree bend and work out.
How long a piece we need in the middle.
Right, so I put that email peace in here and tat it on to now.
Got like a bit of straight hanging off in that so that's sat in nicely
now.
Got clearance everything going to go down.
It will bounce up a little bit but not enough to worry about so with
our other 90 degree bend that there were no need to try and work out
exactly the distance between here and here to put this tailpipe bang
in the middle so
I'm pretty much going to eyeball it getting the
the middle of this band in the middle of the cut-out we can always
trim it so I kind of eyeball it get it roughly in the right position
measure and then I'll cut it for too long and I can easily trim that
off will get it taxed on to this section or probably section actually
this 90-degree section and then I'll just keep trimming it until it's
basically bang in the middle.
Ok, so we've got that straight section cut prepped up cleaned and then
tacked on to the United Arab Emirates going to come out the bumper
tonight.
Just in case of on the car hoping it lines up ok mocking it and then I
can get on so got that on great lineup of roughly where I think it's
going to be about the right place is just a case of permanent marker
in it now one line here and turn around to give me something to light
up with takin' it on now.
That's it all packed up now.
How much are pretty cool looking shape on a step-down out of that
silencer and then runs parallel along the back bumper and then and out
it will kind of sit on the car.
So you should have a little bit from the bump which is quite cool.
So it goes in here and then slide up the titanium so light.
I don't need to clamp the the clamp holder position if that was saying
this far away from you slip joint it be hanging down under its own
way, so that's one of the things that Titanium X superlight this tip
section so I think is I'm going to get an offcut piece of 3 and a half
in tube.
Try and persuade it out for Super 4-inch, Tube and then you just use a
kind of 1452.
That's been that cut a slight angle to give us a slight flashcut as it
comes out for in time to fill that overlook feel that kind of
trapezium shape a little bit better.
So yeah some more materials now.
It's looking pretty.
right, so decided to go for
Keeping it 3 and half inch on the tip looks a bit cleaners and
stepping it up a size got far to do it so I think it was good looking
a bit messy to step it up.
So going to go for kind of the same angle as the bumper and then tap
that on and then we're ready to start his eyes in process.
Right, so we've got that then you still got the tip well done on or
tax on sorry.
Gone for that kind of 3 and a half in finish.
I think that will work really well triple check it for weld it up.
That's all of the kanarya tip section fabricated or packed up as it
were so they say now we're going to have a go at this anodising so
we've had a bit of a play with it.
We getting some results.
We need to work on it and yeah.
I think we can definitely get better, but the idea is beginner
anodised this reaction and then weld it and that will give us some
kind of golden stripes around what will be kind of purple ebluey
titanium rear section.
Look really unique we are building this hasn't worn off if you do
shout very quickly so yeah like the fact.
It's going to be a one-off doing something really unique and a tips
action should come out really well, so it'll be getting on that get on
with that in the next episode so thanks for watching the video give us
a thumbs up.
See you next time.
