Not a super (or any other) tuner, but have been through several tests and dyno bouts with different pipe systems (including changing out elements within 2:1 systems as well as within 2:2 systems), and long phone visits with the techs of 5 different system manufacturers; and short of posting the detail sheets at this point, suffice to say that I agree with looks and sound of previous sentiments regarding 2:2 vs. 2:1 systems (with one possible exception) -- 2:2 sounds and looks better to me. The sound is appreciably better (again imho) and the looks just have a better "look" (but this is more subjective... the 'eye of the beholder' etc.)
That said, in my case, the 2:1 produced better power (hp & tq) across the band; came on earlier and stayed longer.
PS: Eshaust thread?
