I have a stainless steel exhaust system that has been made to fit the mk1 Clio with a C1J fitted.
Its in good condition, has a 3" rolled tip tailpipe and one box.
I've not heard it so can't be sure how loud it is or what sort of sound it makes

Could be adapted to fit the 5 possibly but not going to guarenty it would so prefer to say it will fit Clio only

Like £60 for it, collection only
