truggy 2084ss/41021 or 9853ss/41021
buggy 9901ss/41005 or 9886/41021
the 2013 pipe also works pretty well as does thunder tiger or AE 2035 , dynamite 086hs , msr bullit 1005 , dynamite 053mr , ofna 086 w/round header such as 41021 , one of my alltime favs is the 2032 made by rs competitions and jp racing .
there are many that work , im not much of a fan of the jp pipes on novarossi but to each his own
