what impeller for B1

[feartheride]

I have a stock 94 B1 and I want to know what impeller I should put on it.
I have a coffman,s pipe that has been on the shelf for 4 yrs, so I might put that on this summer.
If anyone has one let me know

i am modding a stock b1 also and from my research I have found that a 13/17 pitch impeller is good.....a good freestyle impeller like on sj's. but in all honesty from what i have been reading you are better off spending your money modding other areas as the stock impeller is pretty good unless it is chewed up.
