So I currently have a 2022 IS350. I have been looking and talking with D3 Performance. They sound very legit I actually know someone who has the tune on the same car. I am mainly looking for burbles and pops. I was told they recommended taking off your cats before they blow. If I abuse the burbles and pops they will blow. I don’t necessarily want to take off my cats because of the smell of gas…. Anyone know what I should do or have recommendations?

If I was in the same situation I would find a crashed is350 pay for the oem headers and mid pipe and just rock the tune until they give out and swap them or put headers and leave the secondary cats might last longer like that, but you gotta pay to play either way it’s💵💵
