Welcome my friends.
In the first part of my story about the creation the mufflers for
Maserati gt. I showed you the internal structure of the factory
mufflers and to obtain more powerful sound I remade
it own way . Added vacuum the flap and have the opportunity
to switch the exhaust to quiet mode.
Link to this video story must will emerge where the
here.
And of course she's downstairs. in the video description.
And now your attention propose a second part of.
In it I will talk about a difficult area in the production
custom exhaust system , on the visible part of the iceberg
all of the exhaust, ie about nozzles.
Well, for those who want to reduce viewing time to a minimum
, and who does not hypnotize observe the work of another
human, move on link above . There waiting for you
3 minute video clip about the result of done
works.
And we Drove to the car...
Mmmm, I Think I'm in the wrong place got it!
but this ass can not be left without attention.
I'll go see what it is. such.
Cylinders more in and a half times, engine capacity 6
liters'.
The right body, literate manifold, freaky motor
v12.
They know how to make cars.
And this is understandable, after all This legendary Asten Martin
DB9.
I really hope that with him I have to work, too.
But Back to Maserati.
Oh! Here's the view for me more familiar, now it's her...
So, I made custom silencers in the case of the original
Maserati silencers.
Now we need to create the nozzle.
The owner of the car wanted that is a custom for the attachment of
tubing.
And at first I even doubted in their forces, after all in sale
hundreds of nozzles on any taste.
But the first layout dispelled my doubt.
Two 76mm pipes were the most harmonious material
for the end of the exhaust systems of this machine.
I make nozzles all the time. , and most often I remake
what the purchased, ready to banks with nozzles or separate
nozzles. And most of all hate this process . That's all
mark , you will expose with correct clearances and
while the car is hanging on the lift all looks from below very
beautiful, but you lower it the ground level and everything changes
everything looks crooked and KOs . The shape of the rear
bumpers, angle, everything. it affects perception.
And here begins the main headache.
Move left ,then right , then down, a little deeper
and so on ad infinitum.
But here are two pipes with a cut edges at an angle and centimeter
jumper between them . The the shape of the nozzle will be at
this machine.
Now you need to connect mufflers and tips.
The outputs of the cans and the situation nozzles are not symmetrical
, also different diameters outputs 63 and 50 mm, and nozzles
at all on 76mm and need to do transition.
Moreover, it will be quite sophisticated form .
With a press of 50mm the 63mm pipe is obtained , and
work from 63mm 76mm . Rather slightly less than 76 because
what pipes will be inside nozzles.
Means their need to crush up to 73mm, because the thickness
the walls pipes and a half millimeters.
Now we need to try on the layout by car, then grab
welding this design , then all cut and
back together for fitting.
The result is that such a landmark.
The bottom view is fine with me, side and top view too
good.
But it was simple. make the first part not
difficult, but repeat the same is much more difficult.
And in this case a copy of need to to make the mirror with the preservation of
all corners and gaps.
And if both nozzles mirror connect with each other,
that means everything is smooth.
And you can build a highway on the second jar.
Same curved pipe with the extension on the end
and also put the nozzle.
It turned out beautiful, But....
Pull the silencers together the nozzles are not gonna work right now.
Nozzles need to be fixed in this position, and for
this need to put several tack welding.
And here begins ... A few broken bones
hand and a new limb in the form of tentacles crawls
to the welding spot.
Now one Bank is ready, nozzle fixed
and it can be removed from the car without fear of geometry change.
But banks the two.
And all it is necessary to repeat once time.
But this time, the nozzle should expose not just exactly
, and exactly so as is worth the first nozzle.
If the first nozzle has managed get in here without dancing.
with a tambourine not would cost.
So for the first time in the arena ... Down on one knee , the second
I press the welding pedal., left hand holding torch
, and the right filler wire, and all this blindly because
you can't see shit .... Not impressed???
All right ... but everything turned out smooth and beautiful... although until
the finale is still plowing and plowing.
The remaining pair of tacks already put easier, and
banks assy with nozzles removed on the table.
Now that all geometry set and nozzles are
in the desired position, you can start doing the other
highway to the quiet part the outlet of the muffler.
There are two transition diameter from 50 to 63 and further to 73 mm.
Ha!
Happens and such...
I can already hear your anger. the cries about the lack of
protective housing on the grinder.
About sticking the disks in the turtle and severed fingers.
I know that.
I don't want to set an example. dangerous work with this tool.
So in the future I promise put a protective cover.
I hope I will be able to alter its for convenient and safe
works.
I plan to dedicate this topic a separate video And
once it comes out in light, there will appear on it
link.
For now, just need to change the disk and continue.
Safety Glasses that I have donned )
Silent nozzle pipe also makes a winding
forms.
But work with him much simpler, banks are now
on the table, not hang for bumper under the car.
Tetris of cones and corners the segments are assembled into
something whole.
Love when persists diameter of pipe in all its
bends, so in 99% of cases do not make cuts at an angle
and cutting sector of 90градусного Gib's.
Suppose that in this place is quite does not matter, but better
not to relax.
To stitch all the parts need to without gaps , to
you did not create voltage on the nozzle at the final
welding seams.
In other words to this everything is not taken aside when
welding.
So you have to share mm to change the angles
under which are joined specific.
Finally all the potholders delivered.
And the result is a design desired shape.
But there is still a second such as.
With her sequence of actions is known , and the deal is done
much faster.
And then welding.
I am not a professional welder and cooking without blowing is not
I can, so I always spend extra argon for purging
pipes from inside.
To protect the weld from the reverse sides.
And as experienced welders say on useless work, because
that OTC would still not accept my stucco.
But I'm not going to weld. submarines and cast iron
bridges, a smooth and beautiful the seam on the inner side
pipe me personally very pleases.
So long live blow!
It was sarcasm if that ...
Here you go...
You can have control the fitting on the machine.
And why only half of the case?
Yes because I boiled only hands-free connections
nozzles and making sure the flatness of the design, boldly
I can start the second one. I didn't fry both of them.
nozzles on the muffler, and first welded one, tried on
its on the car now and weld another. when there is access
to all sites, much it's easier to weld all the stitches.
Again useless gas backwater and miserable seams especially
inside the pipe.
Disgustingly smooth , without burnout, and why this
need inside ? Still. no one will ...
But while we are looking for an answer this issue, banks already
ready!!!
My Frankenstein twins. turned out pretty nice.
Of course I had to use them. the welding seams.
But everything turned out harmoniously.
And I think they are quite you can bet on Maserati
even though there may be any machine, from pelvis to
)))) vase.
Upgrade the realistically deshmansky turn out.
Looks all straight, all smooth, symmetrical and aesthetically pleasing.
I am satisfied with the work done , and most importantly happy with the owner
machinery.
we have to win dead battery and check
how it sounds.
Particularly picky am asking put on your headphones or it'll ring.
this tin can will not very clearly audible.
Now closed dampers and this is a quiet mode of operation.
the exhaust gases prstat through the cavity
muffler and fly through external nozzle tubes . Sound
remained characteristic of this motor. By volume
same as he was from the factory.
But now the flaps open. and work both parts of nozzles
. A ragged Sound filled with low frequency. Flow
unhindered through large acoustic camera
and goes outside.
Sorry microphone and headphones not convey this in full
least, or I haven't learned yet to record this sound properly.
Anyway, I did everything wanted to do.
And told about everything that remembered.
And you ask what's interesting , write comments, put
huskies. and if you want me support and motivate
to create new views, then share my videos
with your friends.
And press the bell to don't miss another
roller.
That's all for today ... Good luck, everybody.
