On the dyno at Matt Steen's Victory Engines, we tested straight 1-3/4 dyno headers with a standard collector, Hooker straight 1-3/4" with a Performance Welding merge collector, a set of good 1-5/8" to 1-3/4" step headers with the same merge collector and the Elston Tri-y's.

Average h.p. on the Elston's was up 12. -Al
