Exhaust Sharp Edges
Do the securing bands on a silencer class as sharp edges?
Mine are 1.2mm stainless, and I have filed the edges over to 45°, but I still think there may be a problem. I have seem cars with edging strip, but I
think this would probably melt.
Any suggestions?

Shouldn't do if you can't get your fingernail under them. Put some exhaust bandage round them if you're worried.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

They are very tight to the silencer, and you can rub your hand over they without any risk to your skin

You could make a heat sheild like the Ron Champion books,sheilds heat and sharp edges on the can.

Exhaust bands should be fine, SVA bloke says if it's more than 3mm proud, it needs a radius, if smaller, just needs 'blunting'.

according to my copy of the SVA manual, exterior projections more than 5mm require a 2.5 mm radius. Projections of more than 1.5 mm but less than 5mm
require to be blunted.
Yours seem to dfinately be less than 5 mm so your blunting should be fine.
Note, there may be some question about whether my manual is complete. Someone here implied that it was just an amendment. It calls it self a draft
copy and has 178 pages

It is just the ammendments that were realeased last year to cover the ESVA, and some other stuff for the normal SVA. I have a copy of that too....I
understand the actual manual is quite large!

Mark I wrapped some 5mm rubber floor matting in heat proof cloth (woven glass one side aluminium the other). I then used copper wire to attach the
things round the silencer, clamp etc. Looked crap but stayed on for the duration of the test without melting (few strange smells though).
Funny it fell off about 30 mins after the SVA was over though ?

Ours was worse than that as we used the industrial toggle clips (double banded) and it passed with no problems...

At Exeter, he didn't check mine very closely.

What with the thickness less than 1.5mm and exeter no being too fussy, I think I will leave them as they are. If I get a fail on them, I will take up
some temporary permanent thing to put it right

I downloaded that too, not sure on how it compares to the full manual, but anything so far mentioned on here has been in it! Seems to cover all areas
in some detail, but as you say, it's a draft. I think it will get you close enough to go for the test.

I just bought my copy of the manual the other day and it says exactly that

referring to the bit from the SVA manual above, how is a "protrusion" classified?
If I put my cynical hat on, surely the whole exhaust is a protrusion of more than 5mm, in which case the edges need the right radius!
If I put my logical hat on, the exhaust is the outer part of the car and so the rule applies to that................but then since when has the SVA
test been logical.....................can't have an uncovered bolt on the exhaust but the fact that it will burn anybody that touches it
doesn't matter!!!!!!!!!

This my logical opinion and for all i know colud be very illogical.
The exhoust can is a protrusion and has the correct radious. The exhaust straps are a protrusion from the exhaust can protrusion, and there for are
protrusion in there own right and considered seperately to the rest of the exhaust.
May be total codswalop buyt sounds good to me.

had a read of the SVA manual (again) the other day and it seems side exhausts are classed as the "edge of the car" and checked with the
cone thingy to assess floorline, so the strap would be the only protrusion.
