Long Tube Headers for Chevrolet C7 (2014-2018) 6.2L

High-Flow Long Tube Headers for 2014-2018 Chevrolet Corvette

What it Does: The Long Tube Headers replace the restrictive factory exhaust manifolds on the 2014-2018 Chevrolet Corvette to eliminate exhaust backpressure, optimize cylinder scavenging, and increase horsepower across the powerband.

The Stock Chevrolet Corvette Exhaust Manifold Bottleneck

Factory exhaust manifolds on the C7 Corvette are cast units constrained by packaging and emissions packaging rather than volumetric efficiency. The short, unevenly sized runner layout causes exhaust gas pulses to collide directly outside the cylinder head ports. This design generates substantial backpressure, traps excess heat in the cylinder heads, and inhibits thermal evacuation—severely restricting high-RPM horsepower on naturally aspirated LT1 engines and accelerating heat soak on supercharged LT4 applications.

The Engineering Solution

Engineered with extended, mandrel-bent T304 stainless steel primary runners, these long tube headers direct exhaust pulses smoothly into high-velocity merge collectors. This architecture creates a scavenging vacuum that pulls spent gases from the combustion chamber, improving cylinder fill during intake valve overlap. Featuring precision TIG-welded joints, thick warp-resistant flanges, and tailored tube geometry, they clear the tight steering shaft and frame rails of the C7 platform while withstanding extreme thermal expansion under track-level duty cycles.
