Thanks for the support legends!
Cool to see the side by side weight savings 👌🏽
No problem 👍👍
That exhaust tip is going to be a trend 😂
Already thinking about doing it hahaha.
ya right maybe in down under where dumbest shit gets the best rap
I did a tip exactly like that in SS on a friends car like 13 years ago. Im glad to see something like it again
The Driver mod is the best mod so far, Good on you Hawkins,
Great work on the exhaust and explaining the differences between materials.
It’s so nice to see someone actually admit that titanium exhausts often sound like crap. People don’t realise that because titanium pipe typically has less than half the wall thickness of a comparable stainless piece that the titanium exhaust actually bleed sound through the walls of the pipe. When you add to that potential resonance issues they can be just horrible. The length of the straight sections also effects the particular frequency it will resonate at which is why free-flowing exhausts with long straight sections get terrible drone. Great for performance/flow though.
You can make them sound good but it takes some serious effort testing different lengths, bends, resonators, maybe even heimholtz devices etc etc. Doing all that r+d to get their titanium systems to sound nice is partly why the big brands like akrapovic are so expensive. They other part is they just charge whatever the market will pay. Lol
Anyway, great vid and it was such a shock to see someone actually tell the truth about how and why different metals sound they way they so. The nicest sounding exhaust I’ve ever had was mild steel and I think part of that was the wall thickness. And I say that as a guy with a titanium exhaust on my GTR (sounds crap everywhere but high rpm), an akra on my bmw (sounds amazing). In fact the 4inch titanium exhaust on my GTR (with a big cannon type muffler) is louder and more offensive than the straight pipe exhaust on my other GTR which is just 3.5inch stainless pipe to the diff then a 3 inch mild steel pipe for the last bit. There’s a fair bit of science behind how an exhaust sounds.
Bro it has no silencers that’s why it sounds like that 💀
For sure, that’s basically it I guess my point is even without adding resonators or mufflers changing the pipe diameter or material type, wall thickness, where and what radius the bends are etc can dramatically change how an exhaust sounds. I agree all straight pipe exhausts have sound characteristics that you can’t really change without adding resonators or mufflers. But there’s a lot of factors behind why a certain exhaust sounds a certain way.
Mild steel sounds the best
Some of my favourite exhausts have been mild steel. Being thicker walled tube gives a mellow/melodic character and more muted resonance. I guess my point is that while each material gives its own character to the exhaust, you can make a nice sounding exhaust or terrible one out of all 3.
Did you say its a crap of civ? Why?
Hawko obviously looks great and lean, but RESPECT for being 10kg down!
Driver mods.
It’s a big NO for that tip
right like thats a middle schoolers dream exhaust. no class no maturity
Looks hideous
To much hate in these comments, who cares that the exhaust isnt backpurged, who cares that the tip isnt what you like, its not your car. This is a fun car and and entertaining build, keep up the good work guys
Exactly. The exhaust goes on for track work and comes off for street use
Exactly mate! People seem to miss the point a lot on this channel.
@@MotiveVideo Do you have a dB reading stock/vs new pipe?
Grub's face on first fire up 😂😂😂
That bonnet 😂🤣 matches the tip perfectly.
This is just what I was looking for and all I searched was custom titanium exhaust build. I drive a gr corolla for 7 months now
You have to back purge titanium.
That exhaust tip will trigger so many internet trolls lol.
The sound takes me back to the early 00s haha
fart cannons?
i cant wait to hear this thing going around bathurst
"that sounds terrible" you are correct there lol
Idle = Terrible. On Gate gunna sound absolutely lethal 👌
That exhaust tip is hilarious!
Rally car noises!
that weight loss isn't solely attributed to the use of titanium its also due to the removal of the catalytic converts
which you can also do with a stainless or aluminum exhaust.
uuuuf the turbo spools sound nice
Just be prepared for the scrutineers to knock back the tip. They may not, but be prepared. Looking forward to seeing the split times across the top of the mountain, especially on day two as you get more confidence with each session!
Party on !!! Full reverb frequency!!!
It's funny the stock exhaust weight about 12 kg, stainless steel exhaust 17.5 kg.
Sometime make you wonder for better flow and sound exchange for weight is it a really good thing. At least if you willing to get titanium exhaust.
Ik lol, the GR Yaris along other well engineered modern performance already have pretty light exhaust systems from the factory, much different from the older generations of performance cars.
yeah light is right!
Love that exhaust tip, something different 👌🏻
Looks shit
I see “titanium exhaust” I click…simple really 🔥💯
I like the sound ngl 😂
That's atrocious, I love it.
Ok ! It’s good for 500hp ! But I rather add a little weight for better sounding 500hp!
Please make that exhaust sound better. Possibly a resonator??
Nice sorts… except the tip… I can’t stroke it.
Hawko good work on the weight reduction looking good mate
Thats cool lol grub is fantastic
Haha sounds funny. Nice work
Hahaha! Good job on that exhaust!
Omg that tip🤣
my god is sounds terrible... But 13kg's is a hell of a good weight savings on something like that. and that tip's pretty awesome.
Another great video
Hope the exhaust was backpurged. Had to deal with remaking an exhaust after the previous person didnt backpurge it cracked after 1 track day kind of a sad life for such an expensive material
No it wasn't... you can see by the white oxide inside the pipe on the welds, it should be silver with no discoloration
@@ivanbajac3536 im aware, its now brittled and wont last long unfortunately it was more of a "i know its not but shouldve been" type of response
It would be sealed on the end with tape with a small hole to allow gas flow or some kind of cap otherwise you'd have to use a huge amount of argon with just an open tube. Adding to that, as long as you don't weld too hot and don't get too much oxidisation on the inside it should be fine with enough filler wire added.
@@vlt873 read my other comment. After welding titanium what you said is a lie. It must be backpurged or the weld becomes extremely brittle regaurdless of how much filler your using. Titanium will crack at the edges of the weld. You might be thinking of stainless which if you dont overheat the "sugaring" will be less
@@Nam_Nguyen2308 I've welded titanium, even stainless to titanium without catastrophic failure causing the exhaust to fall off and cause a major pile up. In an ideal world, yes back purge. While we're arguing the toss about welding technique on the internet, he's probably doing laps of a circuit with his exhaust apparently about to have a catastrophic failure, not giving two f__ks and having a blast.
What a tip!!
Isn't removing weight also changing the centre of gravity.. low weight is good.
Where is hawkos reaction to the exhaust
No purge?
For those wanting to change exhaust on the stock turbo setup, Toyota will not replace the cracked turbo oil drain under warranty.
Could you clarify what you mean by cracked turbo oil drain? 🤔
@@SasanSB12 There have been a few oil drain pipes cracking near the connection at the block. They are a solid pipe and apparently the different exhaust puts different stress on it. Haven't read the bulletin, just what I've been told when one came in for an oil leak. There is foam insulation around it so may not be noticeable straight away until the foam fills with oil.
No back purge?
How much extra does mild steel weigh compared to stainless? Because I got a dual 3” mild steel for my car (a V8) and it seemed to weigh a tonne.
Stainless is pretty much the same weight as mild steel.
stainless steel (316) is 3.5% heavier than mild steel
@@salloroc20 While titanium is 55% lighter than stainless, as seen in video. 2:04 "Just over half the weight"... UHHH, NO, 45% of the weight is less than half, clearly. 55% lighter.
Please change the bonnet back to black! That looked awesome. I watch every of your videos, you put in so much time, knowledge, money, enthusiasm... you inspire me, ruining my GR Yaris original state, once I get it....
Joke exhaust tip aside, removing that black plastic and explosing the rear subframe and whatnot is a really great look.
I’ll give you a tip , Take that one off ! 😂
what are you talking about ? that sound fn good as , ahahhaah good work
Back purge would have been a better idea to avoid the sugaring.
Dude This music is awesome. Where can I find non copyrighted music like this.
You have to buy it mate. We get most of it from audiojungle.com
why do you guys not use pipe benders? instead of pie cuts?
heavy machinery is needed to mandrel bend 3" tubing, let alone titanium
What is the black resonator on the stainless system?
Wheres the reaction vid from Andrew
braaap stustustu
Eshay tip
Cant you wrap the exhaust to help with the tinging
I always found titanium sounds better
This guy is so funny. Hahaha.
Next episode 30kg 4 foot Asian woman driving it down the strip to save weight
Whats with the tip? Someone jam somthing in there?
sounds like a straight piped sohc honda 😂 but function>form
Don't know how much longer it's going to remain street registered before it gets a red sticker lol
What's the diet hawko?
Only way to weld stainless and titanium is to purge otherwise your wasting your money
Sounds like half of a mang-mang, should we call it a mung?
Lol those shorts.... how was your bike ride?
Dont worry it was already the worst sounding yaris before the titanium... but its built for purpose and what a machine it is
Is it straight piped? I hope not
It obviously is.
Nope. Pie-cut "S" bends.
Straight pipe means no muffling.
@@toy200sx but sometimes it is also a CAT delete. Dont do that. Muffler delets are cool but no cat delete please
@@toy200sx Samuel, I was being facetious ;) Would you be Hungarian?
Not as sexy, but I assume you've put on a little lithium motorcycle Battery if you want to save easy and cheap 10kg or so? My battery weighs 1.3 kg and easily starts a 1.8 L 4 cyl with11.5:1 CR. So jealous of Bathurst trip, enjoy!
They mention and show a smaller battery mounted to the boot floor.
Bgm plz
Weight saving is great, but the sound is... Not so good. The tip doesn't suit the car imo, a plain round tip would be smarter
Really cant believe that 1mm titanium has half the weight of 1mm stainless. 🤔
Here's a tip. Don't have a tip like that. 🙄
Double Eww. Looks trash, sounds trash.
It'd better come with ear plugs.
I think I'd rather it be 12kg heavier and a car I liked to drive.
the driver could lose 12kg instead at that point and bobs your uncle the corner balance is the same
Has Andrew been on the track day raw chicken diet?
I feel bad I made fun of your weight and now I want to apologize and tell you that I'm happy for your weight loss
goddamn Toyota cannot make a good sounding 4cyl since the 4AGE. even after I put a turbo on my 2ARFE it was still lackluster, and the 2020 Supra 4cyl sucks too
Maybe because this is a 3 cylinder
You clearly haven’t heard a 2ZZ or 3SGE Beams before
Lmao, its awful sounding. I love it.
2:04 "Just over half the weight"... UHHH, NO, 45% of the weight is less than half, clearly... and Why did you go with a 3"??? That's waaay to small. If you were going for 300hp, then ok. But, if you are going to be crossing 400hp, then a 3.5" is best... I know you can't predict the future, but you end up crossing 500hp... A 3.5" at that level of hp, you would gain 100hp!!! I haven't seen all the videos, but I REALLY REALLY HOPE you changed it to a 3.5" exhaust.
It sounds like a civic 😂
That sounds Gross at Idle . Worse than a P plater Golf !!
Almost like half a mang V6 when you Rev it !
What is the cost of the titanium though? that tip looks and sounds shit! do it again.
that does sound like ass, but them weight losses!
That tip looks stupid AF 🤣 But who cares?
Sorry dont like the tip 😅😖
Sounds like a fart in a tin can
Moist
Please man up and call it tit-anium, you don’t have to be embarrassed! You’re Aussie blokes, not Yankies who call it tie-tanium because they’re scared of saying tit!
Huh? It's tie taniem in Australia
@@sexyfacenation It’s not tie-tanium and it never has been, no matter where you come from. The word has been dumbed down by people who worry about saying a word with “tit” in it.
@@biaggi150 you are cooked mate.
@@sexyfacenation cool!
@@biaggi150 tit. I said it not even scared.
Sounds awful lol
