i know this is an odd question. my wife loves the new G35 but wants it quieter. before i buy, is there any one who has put on a quieter muffler? or has any info or ideas. thanks

 

The exaust sound is great, but if its too loud for you, here is what I recomend. Buy some dynamatt(spelling?) or b-quite and sound dampen the trunk. This will cut down on road noise and also exaust. The exaust that comes with the G35 is actually pretty good. It has variable output and some other nice things. If you dont change the muffler and dampen the trunk you can still roll all the windows down and hear that sweet sweet sound.

 

Tell her you'll get it fixed after you buy it... truth is, she'll just get used to it. She's just not used to the sportiness of the sound. She'll grow to like it.



If she's really that averse to the sound, you might should be looking at other vehicles. The G35 is also going to introduce more road noise, more responsive road feedback, etc... all the price you pay for decent handling and performance, at the expense of luxury/quietness/isolation. The TL or ES may be better options.

 

Yeah, I'd say go w/ a different car then...try toyota or lexus (IS 25O/350)?

 

I recently drove an 05 Sedan as a loaner after dropping my car off for service. The car is whisper quiet compared to my sedan.

The car might sound loud when you sit in it the first time, but after a few weeks, it gets too quiet.. hence why I made mines louder

 

I think infiniti went to a lot of effort to make the engine in this car feel and sound sporty. It is not just exhaust, but comes from all around with noise and vibration.


My wife has a maxima with a very similar VQ. It is silent and smooth all the way to redline, with no vibration or harshness that you can feel or hear. The G35 you can feel the engine through the seats, pedals, floor, etc. Granted it has a few less HP, but not that much.

My last maxima was a 5 speed and other than a little vibration through the clutch pedal all was smooth and silent.

I believe that the noise in the G35 appeals to people and Infiniti engineered it in. There really isn't much wind noise (in mine anyway), it's mostly mechanical.

 

you are feeling the vibrations directly from the engine through the transmission being that it is rear wheel drive (more of the cars unibody structure as to soak up the vibrations too)... my 2k2 6spd maxima is whisper quiet (only screams at 3500+ rpm to redline due to Injen Intake) and the stick has little to no vibrations being that it is fwd and cable actuated shifter...clutch is definitely softer too...twice as soft as g35... I just love the deep idle sound of the g... will work on mods later after break-in...

 

Heh... That's my favorite part about my G35x. I love that the whole car picks up a slight vibration from the engine when you press the gas hard. The scream from the engine is a nice bonus as well.

 

you can try to use dynamat in the trunk and doors to help control the sound level. i've read it makes a significant difference.
