Hey im new to the forum and i just bought a 2001 berlina black s2000. Im curious, what have you guys done to reduce road noise inside your cabins ? The exhaust on my s2k is god-awfully loud (straight-piped) and i already have plans for a quieter cat-back, but i would like to reduce road noise as much as possible so that i can hear my music/passenger on roadtrips. I know there are products such as Dynamat and spray-on sound deadeners, but what would you guys recommend i do?

 

Interested in this as well. I haven't actually done anything besides buy a hard top.. but I haven't even gotten it yet so I don't know how effective it'll be.

I have two 2 hour commutes every weekend so driving with the top up was horrendous. I replaced the top because I thought that was the problem, but it turns out that it still is really loud. Now I have a soft top I don't know what to do with.

I have heard that a hard top will reduce the wind noise, but I imagine that there is still going to be a significant amount of road noise from the tires. I don't know anything about noise deadening materials so I haven't tried anything yet but hopefully someone can help

 

A few months back I completely dynamatted(Vibration) my s2k's floor pan and door skins. 2 layers on the floor pan, 1 on the door skins. I also applied some 3/8 auto insulation foam on top of the dynamat to block acoustical sounds(Sounds coming from outside). I'll say the road noise was reduced a lot(noticeable)but not eliminated. I hadn't got around to doing the trunk yet so I'm there is still quite a bit of sound coming from back there. As for the HT question, I wouldn't know, as I do not have one. I would assume with an insulated HT, road noise would be drastically reduced. S4play dynamatted a couple of his s2ks, may wanna shoot him a pm.
Dynamat

3/8 auto temp and sound insulation

2 layers of mat

2 layers of mat + insulation(Transmission tunnel still not completed)

Interior sorta reinstalled

 

Cool, thanks for the advice guys. A mugen hardtop is next on my list and i hadnt considered lining it with Dynamat, im sure that would help immensely. Do you guys know of a cheaper alternative to Dynamat or does anything even compare?

 

Want cheap...Search sound deadening Peel and Seal.

 

I'm gonna do this to my s really soon. I'm tired of the road noise

 

Just like an earlier poster I wanted to hear my stereo and my passenger better. I used a product named B-Quiet Ultimate. It is similar to Dynamat but the pricing is more reasonable. I did the floor pan, the tunnel, part of the doors and the trunk. The sound reduction was significant. I also ended up getting an OEM hardtop, which also reduces noise significantly. The soundproofing was not a difficult job at all. I'm very happy with both of these improvements and the only thing I would do differently if I started all over would be to be more thorough with my application of the B-Quiet. I see the poster above was quite thorough and that should produce even better results.

 

MLV should be used for reducing noise I believe.

CLDs like B-Quiet are for reducing vibrations.

 

how to reduce car/road noise for a comfortable ride
- get an oem hardtop
- quieter tires
- sound deaden the trunk area, transmission tunnel, passenger seat area, driver's seat area, then 2 doors. Any product is better than no product.
- go back to oem exhaust or a fujitsubo dual with the oem cat or a hfc

if you're still using the stock stereo, get an aftermarket stereo. the stock stereo for all years suck. the early year cars have the worst stereos

 

Very nice suggestions! I actually have a few of those things on your list

I went to great lengths to dynamat everything and went one step further to use a foam rubber liner on top of the Dynamat so my interior carpet feels quite plush almost like home carpet. A good stereo will drown out a lot of the road noise for sure. If you ever wondered how much your car creaks/rattles just drive with the radio off! A good stereo will mask most of those sounds on an older car.

The Fuji exhaust with Berk HFC is amazing combo ~ throaty on WOT but otherwise invisible to passerby's! Really does work, forget all those other exhausts that claim no drone because I call BS. I've used them all and most are super loud, even my old Comptech in my Rio my girl can hear me a block away!
