Got a micron can with the trumpet but its loud as fcuk, is it likely to quieten down much with repacking it?
If so, how much should I be looking at for a repacking kit?
Try acoustafil.
Repacking kits are anything from a tenner to about twenty quid on the bay as you have probably already searched. Scorpion near me in ripley do a roll of packing with sewn edges so its not a bag of loose fibres (which is horrible to pack properly) for £15 a roll and it was more than enough to repack my akra from you matey.
Bought a pack of the loose stuff from Moore Speed Racing for my aprilia for about £12.

Call Mark Hill at MHP ... He'll give you some pointers.
I've repacked a few and found it pretty easy. I've either bought kits from exhaust manufacturers at shows or just a length of replacement matting from ebay. Just a case of drilling out a few rivet heads and buying a cheap rivet kit from Machine mart etc to reassemble. Every one that I have repacked has been dramatically quieter, first thing to try before a baffle if you know its seen more than 3000 miles. Amazing how much it deteriates over just a few thousand miles.
If I didnt want to do it myself then MHP would be where I would send it for either repacking and/or a suitable baffle.
righto guys.
will order some acoutafil (as it's only a tenner) and give it a bash. It's a beaten up old can but a lot lighter than the standard one. If it doesn't work then a MHP replacement can will be on the cards (unless a billy bargain complete system comes up somewhere)
last question (for now)
do the rivets need to be stainless steel? or will alloy ones do?
Got a rivetter? Can loan you one if not.
Stainless and you'll most likely need a scissor type riviter.
Dom, is yours a scissor type?
I repacked mine using a regular cheapie halfords one

Piece of piss, although you do have to be careful not to crush your knuckles when it pops
That's what I have.
Cheers for the offer Dom, for the sake of a tenner I'll just buy one ...
Stripped it out last night...

Good job but how agricultural is that mount !
Fairly, but its all alloy so no huge weight.

I thinking design ... The strap should terminate at the top of the can allowing a single subframe mounting position instead of the forth road bridge assembly that's in place ! Just much much tidier, less parts, fasteners to fall out etc
That maybe true.
But for the total cost of £28.01, including tools to repair said can, I'm not complaining! More cash for shiney sussie bits, innit!

No I agree defo not worth the effort to change now. Was more focused at the original designer that you to be fair.
Hence them going out of business!! :)
Noise test done in industrial estate.
Guess the result...
104
106.8
:(
Ooops
So then.
Baffles, talk to me about them... :rofl:

yep :rofl:
Group buy at MHP it is then
Arrow system a bit loud then?
I tried it on for size when I first got it....sounds great but a lot louder than the Leo Vince, and that won't pass 102 without stuffing the baffle.
Now you guys have me worried about mine :rolleyes:
Did you have to put a lot of the wadding in Millhouse. The akra you sold me I wrapped from the gauze cylinder out to the carbon sleeve.
yeah, but to be fair, it's a very small can!
Did you have the bike warmed up before testing?
Me and a mate tested ours, 2008 r6 decatted with micron can, did 110dB when cold and 102dB when warmed up to 80ish degC. My b1 with stock system with different can did 105-106dB cold and 101-102dB when at 90ish degC.
We used proper noise tester kit, in calibration, followed ACU guidelines etc, so it's a proper reading.
Yeah, warmed it up so temp gauge was "normal" tested it at 50ish cm from pipe exit @45degrees. Then ran it up and down the road onne or twice and retested it.
I'm gonna leave it on for snett anyway and just take the std can as well!
still bit concerned about new can on the blade
my noise test came out much lower than i expected
so had no faith in my figures
but thought fuck it, it was worth the risk :afro:
