After successful runs of the C6 headers, we are finally ready to bring you the C7 8-4-1 system. The same great 8-4-1 sounds, but snappier and more aggressive thanks to the Gen V LT.
Equal Length 8-4-1 Headers (now with double slip joints $$$)
Primaries- 2"
Secondaries- 2.25"
4-1 Collector- 2.25" in/4.5" out
Mid pipe- 4.5" in/ dual 3.15"
Available with or without cats
Custom speced oval cats for maximum surface area
C7 Ultimate NPP- Dual 3.15"
Available with OEM actuator compatible valves (100% OEM control) or vacuum actuators
If you want to run any other exhaust with our headers, you will need to request adapter sleeves in order to be plug and play.
Concept841 uses equal lengths and a single collector to create a uniform exhaust pulse that produces the distinct sound of an even-firing engine. The collector recieves an exhaust pulse every 90 degrees creating continuous scavenging, further amplified by a smaller collector volume.
