Not sure really.
Even with the heat shield on the underside of the can will be contactable.
Whether this will be below the theoretical floor line is difficult to say. It isn't below the actual floor line of the side of the car.
However the heatshied will take trim without it melting.
My other option was to wrap the ends of the can in exhaust wrap or something similar.
Cheers

I've got the Lolocost silencer on a Pinto engine. I didn't bother with a heat shield. Got through SVA fine.
I've also stuck 'U' trim on the leading and trailing edges and it hasn't melted after nearly 1000miles.
HTH,
James

I think I'll do both - i.e. trin the can and the heatshield with U trim and see how I get on.
Thanks

well I almost got mine through so learing from me should help ya!
firstly stuff is not tested from below the floor line so you don't need to worry.
secondly a heat shield is not required - I think there are problems in getting one through - I took mine off.
Now the problem is the can edges at the front and back, and the support piece on yours.
to get round those, make an ali cone; base has littlel tabs the go inside the can ege and the other end a hose clip secures them - to get round edging
on the hose clip, use exhuast paste.
mine failed on the rubber not being durable - I put that on the can edge in an attempt to smooth the transition from can to cone; using exhaust paste
may have go past that.
I will post photos as it is quite enlightening - if your metal fabrication is accurate enough, you may get it past with out any filler (mine was done
on the last day prior to SVA)

Thanks and congratulations - not a bad result, and at least now you have a list to work to.
I had thought about a cone to hide the sharp edges, but was going to see how I got on.
I think I'll have a go at making one after your experience as I have plenty of time.
It seems crazy that some centre are happy with a bit of rubber trim whilst others are not.
When you say stuff isn't tested below the floor line, did you mean the theoretical floor line or the bottom of the side panel?
The bottom of my exhaust is above the bottom of the side panel, although I could easily lower it.
I'd be interested to see your photos of the cone.
Cheers
Stu
