REMARK x Zero Auto Factory Cat-Back Exhaust Honda S2000 (AP1/AP2)

REMARK x Zero Auto Factory Cat-Back Exhaust - Honda S2000 (AP1/AP2) - EQZ-Spec Helmholtz Chamber

Born from a collaboration between REMARK and Zero Auto Factory — a California-based Honda S2000 specialist — the EQZ-Spec cat-back is built around a clever Helmholtz chamber design that lets you tune your exhaust note without swapping any hardware. Full T304 stainless steel construction, hand TIG welded, and engineered for the S2000 platform from the ground up.

This listing covers the REMARK x Zero Auto Factory EQZ-Spec cat-back exhaust system for the 2000–2009 Honda S2000, spanning both the AP1 (2000–2003, 2.0L F20C) and AP2 (2004–2009, 2.2L F22C) chassis variants. One system suits both platforms.
