2007 g35 exhaust noise, dealer says normal

[codij]

Notice more when car is cold.Give it some gas from a rolling start and you hear it.the dealer said normal, they tested all their loaner and demo cars, and they all did the same thing.

FYI

Huh? Do you mean the deeper noise it produces? My assumption is more air is compressed when its cold so you get a deeper note, though, I rather have a Fujita CAI.

No, it sounds like a heat shield rattle

i've heard it before on mine. i have an 07 with 2,300 miles. told me it was normal also.

All I can hear on my is a deeper tone for a first minute. I do love it tho.

my '06 coupe does this for a split second occasionally on a cold start when the engine revs up. last time i had it in for an oil change they let me get under it while it was on the hoist. i could not find anything loose, so i just assume it's the nature of the beast.

yea i like the deeper tone to zozo

Just because every Infinti car does it doesn't mean its normal. A lot f 05-06 Rev-Up motors burn oil. Dealer says "its normal". haha
