hey guys. honestly i would like to know what you all think of the zzp headers? ive looked at them and they dont seem like that bad of a product, and ive seen the midlength header,dp combo in person and i was impressed......

has anyone dyno'd with the zzp set ups? wether its the mid length header dp combo or the stubby with a dp... just looking to see basic numbers.
