Would like to know more about how you get it like that and is it healthy for the car ?

Interesting, you're in Riyadh I'm in Jeddah

Would be interested to see how it sounds being driven around normally, because if it's backfiring like that all the time then it's overkill.

If it only pops from time to time then I might be interested

Look up Mforce.ca on instagram. They say that they can adjust the "popping" to your liking and apparently their tune does increase HP and trq as well

Looking forward to RRs input. If it’s easy and safe, maybe they would have done it by now? I like popping and crackling, but not sure if it sounds good in that video.

Agreed. I little overrun now and then would be nice, but what's in the video seem a little excessive to me.

Isn't too much of this bad for fuel economy and the catalyst converters since they are sending too much un-burned fuel to the exhaust?

Not a good idea at all, even more so with the separated muffler tip/bumper design of the ISF. Decel fuel is essential turned off, with abnormal timing which will dump fuel into the exhaust and spark with the exhaust valves partially open. Excessive fuel vapor gets stuck between the bumper area and you burn the car down. Multiple GT-Rs have burnt from "pop corn" tunes, won't take long on youtube finding Lambos burning down from it.

I have seen numerous burning lambo videos. Didn’t realize that was from a tune. I’ll pass.

lots of cars tune for sound. You can buy a cam tune for mustangs. Makes them sound cammed. They lope, but it’s just a tune.

In my motorcycle tuning days, making sounds like that was the hallmark of a really bad tune. Most guys were embarrassed when their bikes backfired like that.

We have one of the last remaining good sounding cars with everything going FI...

These tunes make your car sound like it’s running on par with a Harley. No thanks.

I love the popping but I love the way it sounds right now with RR Tune Novel Headers and Greddy Ti exhaust (no cats)

I'm pretty sure everyone who's not legally deaf would like the way your setup sounds.
