In 1987 American Honda commissioned DC Sports to develop a header for SCCA-prepped CRX. What culminated was our first 4-into-1 header design, and it was so well received that Honda requested headers for other applications. That system is the one that started it all.

Key Features

• Dyno tuned and tested against competition for maximum performance
• CAD-rendered, race inspired 4-into-1 design emphasizes top-end power for road racing applications
• 2" collector (street legal header)
• 2.5" collector (race use only header)
• 50 state legal or pending legality
• Mild steel ceramic coating  (includes flanges)
• CNC mandrel bends with robotically welded fittings deliver perfect fit
• Equal length primary piping ensures optimum tuning for more power across RPM range
• Unique merge collector design ensures smooth exhaust gas flow
• Comprehensive installation instructions, all necessary hardware and decals included

Vehicle Applications:

• 97-01 USDM* Acura Integra Type-R (1.8L) - 50 state street legal (CARB)
• 98-01 JDM** Integra Type-R (1.8L) w/2.5" collector - For race use only
• 94-97 Delsol Si VTEC DOHC (1.6L) / 99-00 Civic Si - 50 state street legal (CARB)
  
• 94-97 Delsol Si VTEC DOHC (1.6L) / 99-00 Civic Si w/2.5" collector - For race use only

* 97-01 USDM Integra Type-R street legal header is made for the US market Integra-R vehicle fitment which has a 2" sized collector and is slightly shorter length down pipe section compared to the JDM Type-R 4-1 header w/2.5" collector.
** 98-01 JDM Integra-R use a 2.5 collector and has a longer length down pipe section. If fitting to a USDM Integra-R modifications to the B-pipe will be required.
