Re: Mickey Thompson 4-2-1 Headers "Tri-Y"

Small long tubes, 4-2-1 design, Collector that isn't grossly oversized... I'm thinking header designers were pretty smart back then. The 4-2-1 with a tight "choke" at the collector seems to be the way many custom headers are going these days. Just check out Engine Masters competition.

I'm running some Doug's 4-2-1 headers on my Chevy II. Doug's / Doug Thorley has always been a big proponent of Tri-y - maybe they made them?
