I'm surprised at how many would are ok adding weight to the car when so much is done to reduce it.
Different horses for different courses. I use mine as a commuter car for more than an hour each day, so smoothing out some of the rough edges of the elise is definitely worth it for me. I could easily get a more comfortable, quiet car for the commute, but I doubt I could get a car that makes me smile more.

I think you may have misunderstood... I am surprised how many on here want to add weight. Not that I disagree with the notion. I was just surprised. I have a sub-woofer and went from light CF seats back to heavier Probax seats. Both added weight. Nothing wrong with a few pounds to make the car more enjoyable.

for most people, spending all their money to reduce a few lbs of weight with blingy CF parts really doesn't make a whole lot of difference other then posing factor.

Adding a few lbs of sound insulation makes a huge difference in some people's enjoyment driving around normal roads. Esp when you are doing a weekend drive with your significant other who may not appreciate hearing every rattle and exhaust drone. I doubt even the Stig can't feel the difference in handling on the track with the few lbs added. If one really feel the need to remove weight, go take a dump before you go drive and maybe eat a few less burgers.

My Elise noise level definitely is in the loud side. But it is part of my driving experience. Depending on my mood, sometimes I enjoy it and other times it gives me a headache.

For a temporary noise relief I keep a couple of disposable earplugs and I've also tried noise canceling headphones.

For those that have done sound deadening solutions, have you regret doing it so?

Currently running sector111's track pipes.

at least for me, there is really no downside. As long as you only apply it to strategic areas, it just takes out that tin can feel out of driving the car. You can still hear the induction noise and exhaust plenty, just less of the road noise.

I agree. The road noise is what I found tiring (ha!) and the crashing sound going over minor potholes and lane divider dots. I don't regret it the sound deadening for a minute, just makes the car more enjoyable.

It is amazing what a little dynamat on the access panel and MLV under the seats can do to the feel of the car. Should have come from the factory like that IMHO.

Updates?

Folks, any updates... improvements? Is it worth doing the inner wheel wells or doors. Any other finds sealing off leaks, noises and rattles?

I recently put the deamplifier under the seats, against the firewall and a few scattered pieces on the gas tank area.... thing. Also placed luxury liner under the seats and the place under the shelf.

Just that addition made a significant difference in the resonance, road noise and chaos in the cab. It didn't necessarily help with the droning exhaust noises but having a VF supercharger, decat and exhaust, I think that just comes with the territory. Even though the exhaust noise wasn't eliminated, I feel like it did help. Instead of straining to have a convo at 60mph, I can talk at a normal level and be heard.

I unfortunately haven't gotten to do the diffuser and under tray of the car yet. I have the material, just lacking the motivation :scratchhead:

The additions I made reduced the noise orgy in the cab and helped with the clangy, tin can noise of the car going over bumps, and I suspect doing the under tray and diffuser will even further improve the feel of the car.

Overall a worthwhile improvement. A lot of work, but worth it.

interesting thread. thank you all for sharing your knowledge. I decided to contribute my 2 cents.
I've found my exige S to be too noisy. and not the good kind of noisy. but the rattling/poor quality/metal box in a washing machine noisy. and I've decided to see whether I can reduce some of the noise down.

I've used Decibel 10th app for iphone to measure sound level before the modifications, and after.

here's what I've found:
- i have installed vibration damper (second skin - damplifier pro) and noise barrier under the seats (second skin - luxury liner pro), and on part of the firewall.
zero changes in Decible 10th app. used the same road, same driving conditions, same hour of the day. (its the route I take every morning).

next, I went after the belly pan and door skins.
I have installed damplifier pro, luxury liner pro, and foamly wall panels inside the door skins.
I've used damplifier pro, and mat spray on the belly pan.

Decible 10th show decrease from 100db to 92db.

the car feels way more civilized. the rattling noise is gone. you can hear mostly the exhaust, some engine noise, and wind noise on highway speeds.
it was also clearly noticeably by my family whenever I call them while driving, they can finally hear me clearly.

color me impressed.

I purchased an elise that had dynamat (or something similar) installed. That and carpet/alcantara. Before I purchased the car I'd thought of it as a drawback and had planned on removing it. After I drove it, I really liked it. I doubt it adds more than 20lbs and it's quieter than my gen 1 miata. Still quick.

I have added sound deadening mat where metal meets metal
Two different, one noico. The other siless, looks like it is no longer made. Think the siless was much cheaper at the time?
