Show original supplier description
The DC Sports MHR4003 is a one-piece, 4-2-1 ceramic race exhaust header engineered for all-out racing performance. Constructed from 304 stainless steel with a ceramic coating, this header is designed to eliminate the catalytic converter for maximum exhaust flow and minimal restriction. The header features CAD-rendered design for easier installation and CNC mandrel bends, ensuring a perfect fit. It includes comprehensive instructions and all necessary hardware for installation. This race header is specifically tuned for racing applications only and is NOT C.A.R.B. exempt. It is noted as being "Not for sale in California." Professional installation is recommended. Fitment applications for the DC Sports MHR4003 include the 2000-2004 Mitsubishi Eclipse (RS, GS models with 2.4L engine). Note that this item is discontinued and unavailable for ordering as new from some sources.
