مصنع العلامة الخاصة. مشعب عادم H-Series Tri-Y H22 H22A

The step-up primary tubes on this Tri-Y header really woke up my H22’s mid-range—you can feel the pull from 4,500 rpm all the way to redline. Fitment was spot-on with no clearance issues against the oil pan. Definitely worth the upgrade if you’re chasing every bit of power out of a stock long block.

Bolted this onto my H22A and the mid-range pull is noticeably stronger than the stock manifold ever was. The Tri-Y routing clears everything fine and the flanges lined up without any grinding. Sounds deeper too, without being obnoxious on the highway.

The step-up design on this Tri-Y really woke up the top end on my H22A, pulls noticeably harder past 5k than the stock manifold ever did. Fitment was spot on and I didn't have to fight any of the bolt holes.
