You could try the Boomba external waste gate.
You mean BOV, unless they've made some crazy kit to externalize the wastegate on these civics.

What's funny about the crackles and pops sounds is that during the development of the Focus RS, they were done with it, almost finalized when the man who signs off on the final design, loved it all..but it was missing the crackles and pops because it was in fact, tuned perfect. In order to get crackles and pops, they had to spray extra fuel into the system, igniting it in the combustion chamber while the exhaust valves are open just to make that sound haha.

Bump!! Its either pulling time or adding time under deceleration. I cant remember right of the top of my head. May have dabble with it a little in a minute.

I think you pull timing and add fuel. I played with it once only adjusting the very left ignition column and the fuel cut delay. I think I got some noise but I feel like I remember it not being a consistent thing, like it might do it might not and it might be a second might be 3... either way I reverted my changes and haven't tried again in probably almost a year.

I second this @KTuner
Not sure it's going to be something the company themselves will want to have their hands directly in seeing as to get the pops we want we are essentially "screwing up" their nice tune... there is no benefit at all to what we are wanting to do, only adding fuel that doesn't need to be there and changing ignition from where they think it should be... just to make noise (don't get me wrong when/if the setting is there I'll take full advantage lol)

Haha yeah I understand it fully, just would be fun if I'm going to a car meet to have this 1.5t sound halfway decent for a few

I don't mean gurgles. I mean pops and cracks. I'm aware of the sounds these engines make with no exhausts and I'm wanting more. I'll post a video of my wants in a sec
