GR Yaris (Gen 2) Armijs GR YARIS MK2

Since today i have finally got everything i need to record very nicely while on the move, both exhaust, intake/engine and interior, all at the same time. Will have to try and film/record something when the weather is nice and dry, and i got the time !

I am proud to present my first fully kitted sound recording, today the final bit fell in place and did my first test. This is what i envisioned for the comparison but alas, i did not want to wait too long, anyway, SOUNDS GREAT ! Now just to fuse it together with a video of sorts and that will be a nice hobby when bored over summer, Tiktoks and what not with PROPER sound quality :love:

 
Well, its on, and its LOUD :ROFLMAO: :ROFLMAO: :ROFLMAO: When i first started it remotely to check for leaks while it was on the car lift, being under and slightly behind the car there was not much of a perceivable difference, on IDLE rpm, and there almost is not.

When i first gave it the beans, let me tell you, even me who does not care much for it, for a second thought it might be too loud now 😅😅
It ROARS now, it feels more quicker and agile on higher revs, more eager to go, you can feel this, over the weekend i will record it properly and make a nice comparison VID, did some new videos, this time with a Decibel meter present, but because of time constraints i did not have much chances to reshoot and the material will be how it is, mainly sound related (sound recorder muting the sound a bit as it was a lil bit too much at times) other than that all is fine. Last thoughts, the electric VALVE is actually doing much more noticeable of a job than before, it really muffles the sound well now when in the closed position when going full throttle.

How would this testpipe fair with teh stock exhaust? Would the sound still be relative silent? I like the car being rather silent so I can drive quite incognito. Do I need a remap after mounting the testpipe? Or will the ECU learn itself with time?

You dont have to do anything, just swap and that is that. Stock exhaust with GPF delete might be enough really for most of us, i might be able to test this on @Marcis car sometime in the future as he is thinking about getting GPF delete first with stock exhaust to test it.

And without further ado: Here it is, i like it with the Valve closed now when i want to be calm, with open its all bets off lol.
But at least now the Valve does something, can really tell the difference especially under load with it closed and open now.
I am happy with the outcome, i can always mix and match after i hear how it sounds on Marcis car in the future.

Thanks for the video! With the valve open it looks like you would get banned from quite a few circuits 😅

I have a GPF delete and stock exhaust, it’s more incognito, cold start is a little louder but idle is nearly identical to stock but under load you get a bit more. I had the full Akrapovic system on my Mk1 with GPF delete and sounded quite like Armijs and that was too loud for me in every sense but didn’t have the valve option obviously. With my current set up, coupled with the Eventuri intake you get far more intake noise in the cabin than exhaust noise. With regards remap with GPF delete I don’t think this is required as the non-eu markets don’t have the GPF anyway and believe the mapping is the same for all cars so led to believe it’s mapped for without the GPF then the GPF is bolted on for certain markets restricting the performance therefore with that in mind changing the GPF for a delete should unleash the genuine performance of the car. (I’m sure someone will correct me if I’m mistaken) I felt the difference immediately in mine, far more responsive with the throttle and a bit more pull.

Would be great if you create a little sound file (inside/outside) if you find some time.

Is there a chance for quick sound clip of this setup from you ? Which GPF delete did you choose ?
 
If I remember it was an ecutek blog that highlighted there was mapping differences between gpf/non gpf cars. They couldn’t decipher what the differences were but I would be surprised these days if you build a car with a gpf and not account for it in the map. I know it’s not monitored and passive but what are people’s fuel trims doing when removed?
 
Top to bottom …. Inside cold start, inside idle/rev, inside idle, outside cold start/idle/rev, outside cold start.

Not as sophisticated as @Armijs as only done on an iPhone but I think you can get the gist.

As my GPF delete was done before any were on the market mine is simply the GPF cut out and a straight through stainless steel professionally welded in place, non-resonated, in the UK we have approved powerflow fabricators which come with a lifetime guarantee and only cost me £250 and kept the GPF just in case I need to put it back in or anything.

Fair point, I’ve not noticed the fuel much as I don’t use it daily but expect it might be using a little more due to the intake which I know I should probably have that mapped in

have not noticed much of a change, maybe slightly lower petrol use

Right, some thoughts of mine put down as you all have noticed this thread has now winded down.

At the moment, and within 9 months since cars delivery. I have done pretty much all i set out in my mind that i want to change on the car.
As it is my daily, and i want it to be reliable, since the beginning i was sure in my mind that all i want to change is cosmetic, audible and functional.

That i have achieved in my oppinion, i have done all i set out to change on the car since i was following it as a ship silhouette on the map across the seas.

It sounds proper, it looks proper, it wont get lowered as the roads are shit, it has functional protection both inside and out, it has a decent horn and lights for the long winter months. It has been protected against stone chips and salt for the most part, and for me it sounds great while still having a catalyst, i even get the occasional pop and bang, which makes it all the more sweeter unlike the cars mapped to BANG BANG BANG BANG BANG ad nauseum when accelerator is released. I wont change the intake, i wont change the intercooler. The power i have now without GPF is more than enough for me where max speed on 95% of our roads is 90 km/h. I am content, i can just set out with a weary smile every morning (sory neighbours, its quite silenter on cold start with valve closed lol ).

Anyway, all this was to say thank you to all of you who followed me on this Journey and having the honour to have one of the first MK2's here, anf the first MK2 thread, your inquiries and encouragement and interest made it all worth it to put it down here, and also things that can be usefull to others. Today 8 months later more or less, the car is at 23 k kilometers, and i hope to drive much more of them with it in the years to come.

So cheers to you all ! And thank you !

From now on i guess most of my posting will be on What i did today thread, and maybe some occasional posts here and there, next likely being the car DVR install beginning of may.

Again, thank you all ! This is a great community :)

From the first time i saw it myself

What an amazing thread and I am sure of real benefit to everyone who like yourself has been lucky enough to find themselves owning one of these amazing cars.
Defo considering the Lazer LED bar. I wonder if it's outside the capabilities of the DIY mechanic though?
I am thinking about getting some winter wheels and tyres (well I have some 18in winter tyres already from my old beemer).
Need to change that horn too as that's a real issue.
Thank you kindly for recording your journey.
