Concept 841 Chevrolet Corvette C8 Stingray / E-Ray 4-1 Equal Length Headers

The Concept 841 4-1 Equal Length Headers are designed for C8 Stingray and E-Ray owners looking to transform the LT2 exhaust note with a more responsive, sharp, motorsport-inspired sound. Rather than focusing solely on maximum volume, this system uses true equal-length primary tubes and a single 4-into-1 collector to control exhaust pulse timing and create a more balanced exhaust note.

Key Features

• True 4-into-1 equal-length header design

• Designed specifically with sound and exhaust pulse balance in mind

True 4-1 Equal Length Design

Unlike conventional header layouts with unequal primary lengths, Concept 841 uses equal-length runners feeding into a single collector.

The goal is to deliver exhaust pulses to the collector at consistent intervals. According to Concept 841, the collector receives an exhaust pulse every 90 degrees, creating continuous scavenging while producing the distinct sound characteristics associated with an even-firing exhaust arrangement.

NASCAR-Inspired Exhaust Note

The 4-1 system is specifically designed for customers looking for a snappy, quick-revving exhaust character that more closely resembles a NASCAR-style X-pipe sound.

This system is not Concept 841's highest-pitched configuration. Customers specifically looking for the more exotic, higher-pitched sound should consider the company's 8-4-1 system instead.

Stainless Steel Construction

The headers are manufactured from stainless steel for durability and resistance to the extreme temperatures generated by the LT2 exhaust system.

Header Heat Blankets Included

A set of header heat blankets is included with the purchase, helping manage radiant heat within the tightly packaged C8 engine compartment.

E-Ray Compatibility

The system is designed for both the C8 Stingray and E-Ray, with an E-Ray EGT bung included for the applicable installation.

The manufacturer page does not specify exact model years, so I would not advertise a year range until Concept 841 confirms it.
