I've been doing a fair few motorway miles recently, with some brilliant quality tarmac giving off quite a rumble at times.
It's one of my pet hates, so I'm thinking about putting in a bit of extra sound deadening / sound proofing.

I've been doing some reading on here and other sites, but I'm still not entirely sure which route to go down.

This isn't a necessity so I don't want to be spending £100's. Dynamat is widely used but seems really expensive.
I've also seen some people use a brush-on sound deadener, but I'd be worried about not being able to remove that.

Would anyone recommend something they've used, or know a cheaper alternative?
Are there guides out there for removing the trim and carpets (I hate snapping clips and having none to replace them).

Cheers!

I used a load of this stuff http://www.caraudiod...olume-pack.html and 2/3rds of a pack was enough for the boot and doors.

Useful thread asking the same question is here: https://www.s2ki.com/...ound-deadening/


Also, get a really good stereo system installed - works wonders.

One more thing - what tyres are fitted, as these can make a huge difference?

I've used that on the doors. Easy as anything to do.

I extensively soundproofed my old car and most had little effect.
All the floor, behind the seats, boot floor all had top quality foil backed soundproofing plus floor and behind seats had extra foil backed felt. Rear wheel arches coated with thick pro quality rubber underseal. I also added extra felt under bonnet and made the original roof liner.

Most effective soundproofing?
Under drivers side carpet above exhaust and behind seats. Add underseal to front of rear arches.
A roof liner makes the car quieter on mways and good heat/cold insulation.
I made a heavy rubber backed carpet to fit into 'well' below rear window-this works well beefing up the thin plastic partition to boot. I found the rest to be purely incremental and not worth the effort.

mine's my daily. I step out of my 530d Sport into the S, they're chalk 'n cheese on a grand scale. But i accept it for its noise flaws. Tiresome cars, Hondas. Should come with a set of ear defenders!
The sound proofing for me seems to be more important behind the roll hoop area and behind glove box, it is a bit irritating. But ho hum...

Still amuses me

I've seen ( and heard ) the difference doing this properly makes, it's noticeable and more importantly, recordable and repeatable, time and time again.

So for the last time, your japscrap rice roadster doesn't have to sound like an almost empty biscuit tin on a cobbled road. Honda OE build quality is poor, the quality of fittings used is poor and the thought given to what would creak against what is sadly lacking. Oh and that got worse in later cars

Yes, and if you compared a fully soundproofed S2000 with my Boxster you would weep.
When the noise insulation is designed in it isolates the noises from the cabin so much better than Blue Peter cut and stick.

Fixed that for you

As i said - under NO illusions about the build quality differences but then I like tinkering and a car that looks the same going both ways doesn't float my boat no matter how much better built it is

I also enjoyed five years of tinkering with my S2000 as documented on here. I have very little negative to say about it but do agree with you about the build quality.

I think the Boxster looks all right, but we are all different
