been looking at test pipes and would like some confirmation if the berk 63.5 mm TP will be compatible with my exhaust (tanabe concept g). the piping diameter for this exhaust is listed as 60/50, which I think means is 60 mm to the split point and then continues on at 50 mm. however, I would feel a whole lot better ordering this part if some of you guys knew for sure.

 

I would call Berk; they've been helpful to me in the past. Also, if your exhaust now bolts to the stock cat, than it will bolt to the Berk one.

 

Does it bolt on it so then I would say yes but call first to make sure.
