So basically the cats have started to crumble (as the standard exhausts do on these) so theres a blow in the exhaust, I have downpipes and test pipes (all new gaskets, stud, nuts etc are with them) sitting around that I bought a while ago to do the work.
My questions are:
1. If I were to fit the test pipes that I have sitting around, would they fit straight onto the standard downpipes? .
2. If the test pipes don't fit (even if they do), can the downpipes be replaced without having to pull the engine?
My Zed is a 1993 manual twin turbo, UK spec 2+2.
Cheers in advance for any help.
