ok heres the background, i have a new pukka S/S exhaust waiting to fit, but it only fits the turbo XR4s not the NASP ones...

i have a ickle tiny blow in my shitty standard 20year old exhaust thats on the car...

its only gotta stay on there for a few weeks so im either gonna leave it blowing, or bodge it up somehow... pointless spending money on it if im gonna swap it very soon

so wot y recon... i cant use one of those clamp things coz its where the pipe goes into one of the boxes... cant be arsed to weld it (well, get a mate to weld it... lol) so i assume pumping the mofo full of paste shit's the best option? but whats to stop it blowing all the paste out 5mins down the road? any ideas for getting it to hold? also what about using gaffertape?

its only gotta last a few weeks (n dont matter if i gotta do it a few times anyway) so not after anything sturdy

ideas? nomatter how stupid they may seem?
