PLM MFG H-series Tri-Y header features a true step up exhaust header design. The four-piece design header delivers low to mid range power while maximizing engine compartment space for this exhaust manifold. The header is ideal for all forms of competition; auto-cross, drag racing and road racing.

Recommended for Preludes and full H-series swapped vehicles such as Accords and 92-00 Civic/94-01 Integra's. Also compatible with JDM H23A VTEC and F20B engine (H22's lil bro).

NOT compatible with H2B swaps!

Note: You will need an aftermarket front cross member or have it notched off to fit in Preludes/Accords.
