Crackles and Pops exhuast
I have a 2012 Camaro LT and I was wondering if there is anything to make it crackle and pop on downshifts and when I let off the throttle.An example of what I mean is the Jaguar F-type S which is a supercharged v6 or even the v6 mustang has a lot of crackle with aftermarket setups.
Here are some video examples. |

I'm not sure on the V6, the LS3 (and maybe L99) does this. And it's actually because of an emissions thing. It's the DFCO (deceleration fuel cut off). When you lift off the throttle it immediately cuts all fuel injectors, so any leftover fuel ends up being really lean and it burns off after the cylinders. I'm guessing the V6 doesn't have DFCO?

If the V6 has a DFCO table in the tuning, you could make it do that, but I kind of doubt it (since it's an emissions thing, and if they needed it they would've installed it).
Maybe ask in the tuning subforum about that, they would know

Straight piped to the catalytic convertors and/or remove the secondary cats.

I think a thing to get more popping would be a more free flowing exhaust. Glasspacks are know for these sounds and I'm not sure if the v6 has an X pipe but removing may increase as well but don't quote me on that.
