Show original supplier description
The American Racing Headers C7-14178300LSNC is a comprehensive long tube header system engineered for 2014-2019 C7 Corvettes, including Stingray, Grand Sport, Z06, and ZR1 models with LT1, LT4, and LT5 engines. The headers are designed with 1-7/8" primaries and a 3" collector, pairing with an off-road X-pipe to maximize exhaust flow and performance potential, even on supercharged applications. It is explicitly noted as an off-road system, and some sources state it is for "Race/Track Use Only." Additionally, there are mentions of "professional installation and tuning" being recommended or available as part of a package, suggesting post-installation adjustments may be necessary for optimal performance and functionality. Some listings also indicate that the system is "Not legal for use in California or other states with similar laws/regulations," implying emissions compliance may be a consideration. It is important to note that while this system is designed for a range of C7 Corvette models, specific fitment details may vary. Buyers should consult the product documentation or ARH for the most accurate compatibility information, especially regarding the standard or performance exhaust options on different trims.
