Thanks for the tip. But doesn't that mean paying someone to remove it, ship it back, and then I still have no exhaust and have to go through the whole rigmarole again? Think I'll give Scorpion a ring tomorrow to see what they say.
Cheers. Actually there was no noise at all when I drove it home today, just this godawful stink! No idea if it's exhaust fumes, paint burning or heat being generated by the two things touching. Whatever, I'm now travelling by bus and taxi until it's sorted.
E-mailed Abbey, so fingers crossed.
