As you can see from the specs pulled off the Pacemaker website, the Competitions, part number PH4480 (the second list show) have small Primaries (by 3mm) and Secondaries (by 4mm) than the Standards, PH4499 (first on list). Same sized outlet. Hope this helps clear things up.

wtf.... i was always todl the comps have larger primaries....

ahh f**k i am way to p****d to discuss this!

Nothing more to discuss, I mean you can't really argue with the dimensions supplied by Pacemaker. I guess who ever told you was talking out of there hole.
