Hello lads!

Long time no see, I started looking at this forum again, since I moved up the waiting queue a little (15th in my country now, what sucks is we only get one GRY a month, but I’m used to waiting at this point 🤣). I was actually just wondering if any of you lads could have an answer to my questions as I can’t find this anywhere online. Does the GRY backfire, like small pops and crackles on overrun or downshifting? I’m coming off of Renault Sports, and will miss this small detail if GRY doesn’t have it 😓 as I can’t find anything on YouTube regarding this.

Thanks lads,
Nia <3

It certainly doesn't in stock form!

I’m guessing only available through the ECU tuning then? That’s a bummer, I hate that over-exagerated overrun burble everytime people lift the throttle, and it keeps popping for 30 seconds haha
 
I think I’ve possibly had the odd pop when shifting up when pushing really hard but nothing regular.

No, never heard so much as a tiny pop, even after a severe caning, the kind that makes your brakes smell.
 
No pops from mine unless I touch the rev limiter 🤭
 
Syvecs and some exhaust can make you famous in your neighbourhood 🤔

I try to get one ignition cut when touching rev limit upon upshifting, fastest 😎
 
Yes it does…

Just a simple 3“ full turboback exhaust with no cat. and no GPF.
No fancy Pops&Bangs Map.

Backfiring is a flaw, why would you desire it?

I don't get these videos were people rev their cars and revel in them sounding broken.

The same applies to turbo fluttering. The people building for it and desiring it actually asking to mechanical obliterate their turbine.

But they like it for the single reason they like pops snf bangs. 'Cause race car.

While things like these are tolerated on a race car because of performance at the cost of reduced endurance, it's neither demanded nor a design goal. On a street car. There is no purposeful reason for this. Maybe people think it's funny. But it's a fake entertaining for them and a annoyance for many other. People are different, so are opinions.

But where to draw the line? A louder exhaust could fall under the same category. Performance cars have a more open less restricted exhaust to reduce back pressure and to let the engine breathe more freely. The byproduct ist higher noise emissions. To be more racy people put a louder exhaust on their car. It's entertaining after all too. And while this could be a annoyance fir others at least it's mist of the time no harm to the engine.

My opinion is, if it's beneficial for my purpose without harming others, I am good to go. My purpose is a responsive, engaging car that's good to drive and technical optimally configured.

If others purpose is to have a freaking bonker machine... feel free. It's yours after all. I just like to remind others, that we all share the same planet. *gpf delete cough*

Anti-lag on a street car is the one I don't understand. In motorsport there is a performance benefit to keeping the turbo wound up, principally to blow exhaust gases onto a diffuser or keep the boost up, but it makes no sense on the street - unless the user wants to waste their turbocharger in the shortest time possible.

This is basically the same car I have, same Akrapovič exhaust. The bangs aren’t excessive, and I think it’s the perfect amount. I was hoping Gr Yaris with Akrapovic would give the same sound

Maybe because of this


in real life Rowan Atkinson destroys you on B-road with Reliant Robin.

Its all about feeling.

Then to the antilag - if it was easy to switch on - yeah I could have it, just for b-road kicks.
Quite sure GR's clutch would die.

one hint - do not try to photograph Rally sprint cars with antilag on from their exhaust side on stage start. It is rather loud place to be.
 
I'm glad you didn't say Mr Bean as he had a Mini ;)

I'm sure in very small doses anti-lag is 'fun', but there are so many components to upgrade and at great expense to make it even a little bit more safe for your car. But then a fool is easily separated from his money. I thought anti-lag seemed to gain in popularity after F1 cars ran exhaust blown diffusers about 10yrs ago.
