I have read somewhere that the 1.3 Copen shares an engine with the 1.3 Yaris of the same age. So any opinons of whether the exhuast manifold form the Yaris might fit? There are a few knocking around andthey look better than the Copen ones. I have seen the thread on this forum talking about fitting the Sirion exhaust manifold but couldn't find any of those. Would be interested to hear what people think.
