i've seen these around for about a tenner,i just wondered how you would fit them to a kit car silencer with the extra bend at the end?

Got a killer to if you want it.

fit it to the pipe at entry

Id try and find an alternative solution if you can, virtually all the decibel killer type silencers kill the noise by severely restricting the flow through them, which means it severely affects performance as well.

better to have a road legal can and an alternate setup for places where you cannot use the race can...
