Discharge Tube Issues

Hey guys, my plans are to run the AFM power pipe inlet, but what discharge should i use. WIll i see a major dif if i use their bypass and discharge kit? Or should i just use one of the paxton or vortech ones.

Also, I run the carb box, and they say that you can use a standard length discharge tube.

BUT, i also run Vic Jr. intake so the box sits a good 2 inches higher, meaning the inlet for it sits 2" higher also.

Anyone who runs a spacer or two, what pipe are you using?

Oh yeah, am I the only one to do this novi 2000+carb box thing...I can't find anyone else who has done this.
