Hello,

I have an 08 g35x 08 sedan with titanium muffler delete, aftermarket y pipe, 16 inch vibrant resonators with stock cats.
After I got my new resonators installed I noticed that I get some aggressive pops when I rev while the car is not moving. However, I do not get any pops when downshifting while driving and was wondering how I could get that to happen.
My car is running rich as well, I think it has something to do with the rpm's not dropping fast enough while driving but that is only a guess.
Is there anyway I can get what I want without a tune? Thanks!

Not really, fuel management is the answer. Don't ever do the "turn the ignition off/on really quick" thing either unless you like replacing O2 sensors.

 

I'm not that desperate hahah! I was just curious, and I dont think thats even possible to do with push to start
