Has anyone tried Motor Mat (http://www.secondskinaudio.com/cgi-...x.cgi?p=ps&pg=4) or any other products on the underside of the hood?
I just opened my 07's hood for the first time today and noticed that it was bare metal. Is there any point? The engine seems quiet anyway.
Do MDXs have sound deadening under the hood?

I used Dynamat's Hoodliner on my '05 Pilot as part of a much more extensive sound deadening project on the vehicle. Quite honestly I could not tell a bit of difference once the hoodliner was installed. The Pilot's V6 is fairly quiet to begin with as you say. But there are also so many other noisier places in the Pilot where I found sound deadening material to be more effective. If the hood is all you are going to do on your Pilot, don't waste your money IMHO. On the otherhand I put Second Skin's Motormat on my son's Escape which has a fairly loud V6 engine and in that case, it definitely did make a difference after it was installed.

Thanks. I will also have it in the doors already, but I probably won't do the hood. I suspect the reason Honda didn't use it there themselves is that it's not very necessary...

The MDX does have an acoustic liner for the hood. However the design of the liner is very different from the reflective liner photo posted above.
As far as installing Dynamat's hoodliner I would be very concerned with the thermal effect it would have on underhood components. The standard liner you normally see manufactures install (eg, MDX) is very porous, and colored black. Thus it absorbs both sound and heat.
If you install a liner that reflects heat back into the engine bay, you gotta wonder if underhood component life would be adversely effected by higher underhood temps, especially during the hottest part of the summer. Those components include plastic and rubber hoses and seals, and, of course, one of the most heat sensitive parts, the battery.
I think I'll stick with what the engineers had in mind. |

Interesting point. Our Corolla also has a soft, black hoodliner (and a noisier engine). I wonder what the reason is that the aftermarket liners are reflective?

Some of the hood insulators are actually a fire supression system that drops onto the engine and extinguishes a fire.

Can you provide some details on your project?
I've done all the mods I want ot my Pilot, and I'm really happy with it except for the road noise. It's not bad, but if I could lower it a bit I would reach nirvana.
I've read some other info on sound deadening, and it seems that for some vehicles it works better than others. I had the vehicle undercoated, and I added a couple cans of rubberized asphault to the underside of the fenderwells. From what I've read, people put sound deadening material on as much of the inner surface of the vehicle as possible. I have no issue with the cost of doing this, if it works, but I'm concerned about getting rattles from having panels and pieces removed and then put back on.
As for engine nows, the Pilot is pefect. I test drove a Highlander, and it has quite the roar off the line. |

That is exactly what I've been looking for!
Great detail on your work, and I'm very happy to hear that there was noise reduction that you are happy with.
Now I just have to find a reputable local shop to do the work for me. :D
Again, thank you. |

I would check out HzEmall in Surrey. Their work is very good - take a look at the online photos. Based on other forums, the owner (Tim) seems like a good guy to deal with. |

My 03 MDX had a lot more road-noise suppression than my 07 Pilot. One place you can actually see is the noted hood ling (or lack thereof).
One other really nice MDX hood feature is that it has two gas struts to hold hood open instead of the "stick."
I'll use the stick and spend the $10K+ (discounted Pilot EX-L vs new 07 MDX) on something else.:) |

Gas hood struts are nice... until they die. My Maxima's died after about 5-6 years, and they wanted to charge me $125 to replace. If you think the metal "stick" is lame, try using an actual stick, which I did for years. :D

I'm looking at 2 shops. The first wants $3K to do the job (1/2 labour, 1/2 parts). Doesn't that seem a little steep?
I'll be calling "hurts-em-all" tomorrow. |

How much material are they estimating (sq. ft) and what brand? Also how long are they estimating the job to take? If I calculated right, $3K CAD is about $2600 USD so $1300 in materials is a little steep. I spent about $350 including shipping for the B-Quiet stuff (ultimate and V-comp). IMO, based on one person doing the work I would estimate 3 days of labor and at a $50 per hour rate, the $1300 quote is close. All in all I would expect to pay around $1600/$1700 USD for what I did. If you do something more extensive like what knapp9 did I would expect something closer to $2K. |

They want $1500 for labour, and $1500 for material. The material is HushMat or Dynamat.
I looked up B-Quiet, as well as some other materials (perhaps some CarQuiet for the hard to reach places, and some additional undercoating). If I did this myself, I could buy B-Quiet, foam, and some spray for about $600.
I believe you stated that you did all the work yourself. Did you have any diagrams of how the interior parts come apart; the exploded views of the components? Do you know of where this type of thing exists? I'd rather do the work myself for $600 than pay $3000. It's not that I can't afford it, but I've always had problem paying too much for anything. |

| I used the Honda service manual published by Helm (www.helminc.com). It gives you the step-by-step procedures on how to removal all of the panels. The last time I checked it was $75 - definitely worth every penny as it shows you almost everything you need to know about the Pilot. |

Great pictures and thanks for sharing your project.
If someone were to try it for themselves, do you have any areas where you don't think it made a difference so you would recommend skipping? Maybe the hood and tailgate? |

Great.
Thanks for all your help - I really appreciate it.

I'd skip the hood, tailgate, roof and probably the floor under the front seats. I'd also use a lot less butyl rubber damp mat and put more faith in the MLV barrier product. After doing 2 vehicles with, and 2 other vehicles without, I am convinced that Vcomp/SS Luxury Liner sort of MLV barrier products are the single best noise killer of all the sound deadening stuff one can buy....IMHO of course. ;) Others may disagree.
If I were on a limited budget and with little time to do the work, I'd put the MLV barrier stuff under the rear seat and rear hatch floor area; and most certainly over the 2 rear wheel wells. If that wasn't enough, then I'd do the 4 doors. That's it...because I feel the biggest source of "road noise" in a Pilot is from the rear of the vehicle.:8: If you got the $$'s and more time, then do something like I did. With sound deadening, "more" usually is "better."
ED27 is right. I could never have done a job like this without the Honda service manual. |

My other car, Mercedes use coil spring to hold the hood. I have it for 12 yrs, still no problem. Wonder why use gas struct instead of coil spring? |
