One mongoose system to fit Nova GTE (and possibly GSi), I had it on my GTE for 6-7 months, was temporarily on another car. It is in stainless, and although a bit dirty, it has no dents or dings that i can remember. It bolts on to the end of the downpipe and finishes in a 3" tailpipe.
£100(was nearly £250 new iirc)
