Tri-Y's suck IMO. Plenty of dyno sheets out there showing 4-1's outperform the Tri-Y marketing gimmick.

Pfadt is still unable to produce a dyno sheet showing how a Tri-Y header is superior to a 4-1. Vengeance racing did a test recently and gained power over the Pfadt header with a 4-1 setup from ARH.. I'm sure a Kooks header would yield similar results.

I buy horsepower, not hype. Clearly, the only thing a Tri-Y header does is add to more hype in an already shady and non-transparent industry.
