I already explained that putting Dynamat in the 09+ FX is not going to help alot. Sure it may quiet it down just a tad bit more, but not to the standard you want it. Everything in the 09+ is double sealed and sound deadened. Not only does the carpet padding have a sound blocker in it, but it also has another layer of floor foam under it sealed to the frame and floor pan. All your going to be doing is adding more weight to the car and tear the interior apart. If you think that aftermarket exhaust you added on is too loud, then go back to OEM.
This is why Infiniti toned the exhaust down on the 2nd gen's cause the 1st gen's suffered from exhaust drone inside the cabin. Plus Infiniti wanted to appeal to different varieties of buyers cause not everyone wants a loud exhaust.
I highly doubt any second gen owner on here is going to rip their new FX apart to do that themselves.

actually i was thinking only putting the dynamat or some sort of foam to prevent the driver side door from rattling whenever i turn the bass up...sorry if that was unclear, i'm not bothered by my exhaust

Haha yeah I know what you mean. The door vibrates when the bass from the stereo is up loud in the car. Mine does it too.
But my post ^^ was directed to the original poster. He had another thread before about the Gemini exhaust he added on being to loud inside of the cabin, so he was wanting to find a way to block it out.

Actually I don't agree with FireOnic3 - Do you actually know any 2nd gens that have tried insulation and said it didn't help? I Seriously doubt it.
Insulation will absolutely help any car. Simple physics - the material attenuates resonance to reduce noise in the cabin...period. Doesn't matter what other kinds of sound deadening materials are already there. In fact, Dynamat actually recommends 3 layers of material in some areas for maximum benefit. - Mat, liner, pad. Adding to what you already have will have an improvement in stereo sound quality and reduced road noise.
Same goes for 1st gen - the OEM sound deadening is present everywhere but a layer of Dynamat absolutely helped mine.
Fact is, all car manufacturers use materials and installation processes with considerations to cost and manufacturability. The OEM sound and vibration attenuation does a good job until you start adding bolt on mods. Then the OEM insulation isn't designed for that level of noise & vibration.
As for "weight" issue - we're driving an SUV. 36 square feet of Dynamat weighs in at about 15 lbs.
The DIY for the 2nd gen is going to be the same as the first gen. Any service manual will tell you how to remove the door panels. I bought my manual for 5 bucks on eBay.
Drone in the 1st gen? Wow - you're the first person I have ever heard say that.

I've driven an 03 FX45 and it did experience alot of exhaust drone at lower RPM's when cruising. It was very relevant when sitting in the second row especially. Maybe it's just that particular FX, but it's just my experience.
Second I do know someone that used something similar to Dynamat on a 2nd gen. My neighbor had something called brown bread and Bquiet stuff, I really don't know what it is but it's a popular alternative to Dynamat with excellent reviews. Anyways the shop that did his stereo install also lined the front and rear seats along with the doors, trunk, and spare tire well. There wasn't a big noticeable difference in road noise when compared to both of our vehicles. The stereo improved drastically, but road noise wasn't reduced any better than what my stock FX is.
Third I never said it won't help the car, but "IMO" and "my experience", I really don't think it's going to make a HUGE impact.
But if by all means he wants to, then let him. I'm just giving an opinion.

That's a bold and very subjective speculation... Have you done it? If not then upon what basis are you drawing these conclusions?
1st gen has this as well. Aftermarket sound deadening material is very different from what is essentially cellulose insulation ("sound blocker") and Styrofoam ("floor foam").
Enough sound insulation to cover the entire FX weighs about 15lbs. Hardly a noticeable amount, especially when it's evenly distributed throughout the vehicle. Removing the interior is a completely reversible process that requires no ripping, tearing, breaking, etc... It requires thought, a few hand tools, care, and patience.
Clearly there is interest in doing this job, as can be seen by the mere existence of this thread.

I have Brown Bread Ultimate in my FX and it made a huge difference. I also installed it correctly, which is hugely important. There are many different products available from both B-quiet and Dynamat that do different things. B-quiet makes a product called "v-comp" that is expressly intended to reduce road noise. What your friend has is meant to reduce resonance and vibrations.

FX45 is not equal to FX35 in any generation. Hard to compare v-8 to v-6 noise levels.
What Tchuck said here.
Fair enough. But you should at least realize your reviews, experiences and opinions were not asked for. The thread was - can you help me DIY dynamat in a 2nd gen? Whole point of threads is to provide relevant help. If there is another thread asking for opinions on weather or not insulation provides benefit - that would be the better place to post.

Great responses, still no DIY. What do you guys think about having Best Buy install the dynamat?
no offense but i :.rofl::.rofl::.rofl: at this question. best buy is not where you want to take your car. they couldn't do the trunk of my honda, much less the entire FX.

DIY:
1. Purchase or otherwise obtain a copy of the manual for your FX model's year.
2. Follow directions for removing door panels or interior trim where you would like to apply insulation
3. Follow Dynamat application instructions (also see note below)
4. Replace door panels/interior trim per manual's direction
Note - you can use the 1st generation DIY as a guide - I doubt you will encounter anything you can't handle. Getting the manual is key because it tells you where all the clips and fasteners are. Dynamat comes with installation instructions general for any car.

When I turn my sub up, ive noticed that the dome light/sunglass holder thing rattles like crazy. The whole thing, all the way until it meets the sunroof rattles and this is the only part I feel like i need dynamated. When I hold my hand tightly to it in order to stop the rattle the sound is so much better.
Too bad it looks so damn hard to take the headliner off :-(

Yeah no sunglasses in there and it still rattles. Maybe mine has defective padding
VERY annoying to say the least.Side note, is there a cheap way to make the license plate stop rattling too? dynamat sells a kit for that but i feel it's a ripoff for the small amount of dynamat you actually get.

Rubber stoppers? Do you have a link where i can get them please?
