I'm collecting the pipes up and I'm still looking for the best dyno place here in Western PA to have em dynoed.
Remember that just as in the Zilla pipe tests, each pipe will perform at its best with porting optimized for that particular pipe as well as proper jetting. You might need to wrangle up 1 or 2 more 250's, with different porting, to use as the dyno mules to gain an understanding of what each pipe likes better.
