Which exhausts DO have decel pop?

I really like the decel pop of my L99. I'd like to get a louder exhaust with that feature. Assuming no other mods, which exhausts continue to pop?

Videos are welcome.

I still had it with my SOLO axleback, SP lt headers, hf cats, and stock resonator.

I dont hear it as much if at all with the cam now.

Do some exhaust systems really quiet the decel pop down enough to not hear it?

The decel pop is from the tune, so any exhaust that is louder than stock will amplify it.

I think all exhausts have the decel pop. Mikeyg36 is correct. I used to like it when I had stock exhaust, but now that I have the Stainless Works retro chambered cat back...it's ridiculously loud! Sounds like I'm tossing out firecrackers out the back when I decel. Can't wait to put on my LT headers and get a tune, so I can get rid of it!

It's the tune, not the exhaust. Changing exhaust shouldn't really add more or less popping. It may change how loud it is.

My wife calls the decel popping "car farts"

Pretty sure it is programmed in the ECU, too predictable regardless of the muffler. I'm sure it is exaggerated with after market mufflers, sound good with the NPP option IMO
