silencer edges
my silencer will fail SVA (in 4 days time) as it does not have the correct radius at the ends - Would putting exhaust wrap on the ends keep Mr SVA
happy or would he be looking for something more permanent
also the silencer is not well sealed and blows out a bit at the end seals - is there some sort of temporary silicon I could use on the outside to seal
it til after SVA
thanks

You could try exhaust putty or exhaust gum

Its probably worth making a cover to fit over the silencer rather than trying to wrap the ends. Hopefully this will cover any sharp edges on your
mounting bracket too.
Try some standard clear silicone on the can anyway. It will harden and fall off eventually but should get you through the test if you are after a
quick fix.

I would say the same. I've used the putty on my bike can around the input pipe after a can rebuild, and it's lasted for months.
Just wet the digit and smooth over for a nicer looking finish 
It looks like the Midget is winning at the moment......

Do you have any pics of the ends of your can?
I might have some nice ali sections that will clip over the end to give you a nice rad...

my bad - I never explained the problem clearly enough
the leak is not at the join between silencer and exhaust but in the silencer itself
if you look at the pic
here it is the outer seal at the end of the can itself (the part missing from
the silencer)
hope I have explained it better
Tegwin - thanks for the offer - my silencer has no edge at at all so there is nothing to clip onto

that's not a silencer it's a tube with a bit of padding round it in another tube. fraid it'll never pass like that, fill the outer
tube with padding then weld a plate on the end

Tegwin - I have the same problem on mine. I have fitted some plastic U-trim, but I hear that Brum test station will reject this. I tried cutting and
bending a piece of ali tub, but it wouldn't bend around the can without kinking. How did you achieve it? I have a small lip, that projects ~5mm
on the back side of the can, where the steel is folded onto itself. Any suggestions?

The easiest way to get over the problem is to build a cage round the silencer. Just weld up some 6mm steel rod that goes well foreword, and back to
cover the offending edges, if Mr SVA's round ball cant touch the edges then the jobs a good un! Plus it may "accidently" fall of
after SVA, (mine did). Cheers Ray

I personaly would make up a simple cone, you need 3 dimensions dia of main body dia of small tube and length between end of main body and end of inner
tube... If i need to make one I just give an old sheet metal worker mate those 3 and he draws me up an opened up template to cut and weld.. sure there
must be some-one on here that could do the neccessary projections.

I cut a piece of 10mm dia copper tube to length, then cut a slot along the length with a nibbler, tap it on with a wood block with join at back. Or
get one of these
