on my two 210's I used Tomos long header coupled to Jamarcol Fuego slide on pipe with a bracket- from Treats-
no welding needed, just get strong clamp from them too, for shim use sliver of exhaust gasket sheet from auto store-
this way it is possible to mantain enough room for pedals and use existing hanger- one bolt is enough
fit is super tight but doable, maybe a little pursuading w/a hammer to slightly flatten it on chain side
you have to cut/drill/dremmel/file/tap the cylinder as explained above or on WIKI (will add pics soon) to use 25mm header, but it is worth the effort, especially if you conically enlarge exhaust port to match the haeder's size...
