D-Series TA Tri-Y Header SOHC D16 D15 2.5" Collector

D series tri Y header

Header bolted on perfectly no issues. From idle sounds more throaty not so much like normal honda rice idle 👍

These headers look awesome

These headers fit nice and tight on my D15B7! I love the way they look and will burn nicely once rubbed with alcohol before first start up.

I combined this header with the 2.5 inch telescoping test pipe which mated perfectly with the 2.5 inch Invidia N1 cat-back exhaust. I like the one-piece manifold which probably helps direct exhaust gas out more efficiently than the previously installed 2 piece header. The bigger primaries and large collector contribute a little more exhaust resonance at lower rpm's, but at cruising speeds of about 3300 rpms in 5th gear...it sounds amazing. It even burbles a bit at downshift. Overall, I am pleased with my purchases and recommend this to anyone looking to complete their cat-back system.
