I had my pop charger installed with the NISMO exhaust and the 6 wire grounding set from insane amine or whatever his screen name is lol....i know there are alot of opinions on all 3 of these mods, but so far i have had the stuff installed for about 2 weeks and i think the car sounds alot better...it has an exotic sound and when you step on the gas (no matter how fast ur going) it gets really nasty! i do think the throttle response is much better too and the car really does seem a little quicker. Also when i was idling before i got the stuff installed it was rough and now it is quiet and sweet...for the money i think these 3 things are really worth it!
I'm not gonna say that these 3 mods are the "best" in their categories bc i have nothing to compare them to, but i just wanted to say that I for one, am really happy with all 3....thanks for all the help everyone who answered all my questions

 

Does the Nismo exhaust drone out all? How do you like the sound of the Popcharger with the Nismo exhaust?

 

No it doesn't drone out at all. I love the sound of the two together. It keeps the same stock sound but just alot louder and deeper (if that makes any sense) When it's idle, you can't really tell the difference at all, but once you start going, even if it is slow, it sounds sweet. Plus it was easy to install
