Im straight piped and decatted from headers to exhaust tip, and i only get one loud pop on decel. Depending on the right conditions, it will pop with a small flame when running e85 mix.
(Also im on stock tune)

Has anyone one accomplished this yet? I plan on going full straight pipes with headers so i was hoping for a little crackle in the rear.

Mine crackles and pops a lot.....

PPE headers, PPE mid pipes with hi-flow race cat’s, H&S exhaust, RR-Racing supercharger and remap.

Will try to capture some video.

Does sound good!

With the RR-Racing bazooka exhaust and tune all you need to do is let the car decel for a few seconds and hit the cruise control. It will pop every single time. Almost sounds like a gun shot sometimes.

^ can confirm. Here's my borla without mufflers, in the video when decelerating you can hear a loud crackle, happens nearly every time downshifting.

An overrun tune would help. Doubtful any of tuning companies like RR would make one though.
