If you're doing FI catback does G3 make a difference?

ped

The most annoying aspect is when you're idling along (in whatever gear) and you need to speed up a little - pushing the throttle 1/4-1/2 way results in horrid resonance inside the car that gives me a headache. Is that mitigated by break-in or does it stay generally the same? If it stays about the same I think I'm going back to stock exhaust.

As for the Stillen G3 - if I go back to stock exhaust is there still a benefit to be had from keeping the G3?

Why are you convinced there is a correlation betwen the two? Keep the intake.

Figured opening exhaust and intake together were necessary to see true benefit. But if you say keeping intake still carries a benefit good. That's why I asked. Thanks...

Just out of curiosity, is your car a 7AT or a 6MT?

7at

Based on what I've read in these forums, the drone tends to be worse on 7at cars. My car is also a 7at, and if I leave it in D or DS mode, the car always shifts to the highest possible gear. This is great for fuel economy, but as you've noticed, it puts you right in the middle of the headache-inducing "drone zone."

To counter this, I've started driving in M mode all the time. By manually shifting the car, I can keep it in a lower gear to avoid the drone. In addition, the lower gear gives me better throttle response when I need to accelerate.

Agreed - I find myself doing the same. Bummer that it negates some of the benefit of having the auto tranny.

This is another time I wish Nissan would wake up and give us a "sports" mode tranny button like the Evo has. Three or four settings for how aggressively you want (or don't want) the tranny to seek out taller gears would go a long way to being ale to stay in D but get the result we're after.
