Barf tube for Hatori Pipe

[freeflyn2001]

Why does the Hatori come with such a large Barf tube coming out of the Pipe. Is it ok the change it to a smaller one of will it affect the performance. My guess is it shouldn't but I just want anothe opinion.

not sure what you are calling a barf tube? I assume you mean the silicon tube that directs oil away from the model. You do NOT want to downsize this tube, either use the one that came with the pipe, or use none. anything else will deflect and constrict the exhaust and kill performance.
