Acousta-fil

any good ?

good stuff

but do use the online calculator as to how much you need, cos without it you will overfill by a long way

also you will have a loud hour or so first run while it settles down

Good stuff

I used the competition version in mine which is more like the traditional matting
Cost about £50 delivered to fill an SBD can

The bonus was you don't have to use stainless steel wire wool with it
Infact they advise specifically against using it with the matting as it causes localised hot spots

IIRC i got mine from a company called savaguard ?

Yup, just filled mine up wioth it. I was 102db before, still running it in so not sure what it is now, but it sounds less harsh already in my 6" can.

Edit: Got mine off eaby as it worked out cheaper
eBay - The UK's Online Marketplace

I have it fitted, but I'm a while off starting it yet... calculator was great, and its dead easy to install.


Jon Ison - 17/3/12 at 05:52 PM

The calculator tells me I need 1.89 meters, seems a lot how thin is it when it goes in ?


Alfa145 - 17/3/12 at 05:58 PM

Thats how much I needed in my 6" can. Its prob 10mm thick at the most, maybe less

Mines 6 inch to, just seems like a lot, guess the photo is misleading it shows it wrapped round the inner pipe just twice which is well less than best part of 2 meters ?

I think thats promotional sales photos for you. Its the same when you order that nice huge juicy Big Mac in the picture, then when you open the box it's tiny, a bit mongy looking and falling apart.

Excellent stuff,
It's knitted together with something like fishing line,which melts after running the engine for a while which then lets it expand to fill the can.

Thanks for the link, just purchased 2 mts.


dave r - 18/3/12 at 07:32 AM

i have taken a can apart a few months after putting this in... and its amazing how much it expands


Jon Ison - 22/3/12 at 05:38 PM

Update,

Installed the stuff not surprisingly after what came out it was imidiatly quieter, now it's bedding in its super quiet considering it as 10000 rpm propelled exhaust gas passing through it.

Highly recommended.

That looks like a great idea. I had a horrible job repacking the Akropovic cans on my RSV1000 last year, wish I'd know about this back than.


Daddylonglegs - 26/3/12 at 11:32 AM

Been thinking of repacking my exhaust with this stuff. I used the calculator but the problem is my can is a Blueflame twin-port, so the inner perforated pipe splits about 1/2 way along into 2 for the outlet. Not sure how to calculate for that.

Any ideas anyone?

just had my delivery of acousta-fil today, just about to do the job now - will update for those people wondering whether to get it or not


yellowcab - 27/3/12 at 03:43 PM

well that was much easier than anticipated, however slightly disappointing to see that my exhaust can (which I thought was empty) was actually full of wadding already, albeit broken down and filthy - but I still wanted it to be empty.

put it all back together, and ran it for a wee while, can't say I've noticed a difference as yet - as there is a slow blow between joints which I will sort out... but apparently it gets quieter the more its driven.

cheers all


yellowcab - 28/3/12 at 11:15 AM

being honest I wasn't sure how much to put in, but I did the calculator thing on their website, so I just put in the amount they stated...

here are some pics of the process for those that can tell me I've done it wrong lol
