Exhaust Headers for Chevrolet Corvette C5 (2005-2013)

High-Flow Long Tube Exhaust Headers for 2005-2013 Chevrolet Corvette

These 1 7/8-inch long tube stainless steel exhaust headers replace the restrictive factory cast manifolds to maximize exhaust scavenging and significantly increase high-RPM horsepower.

The Stock Corvette Restraint

The OEM cast iron exhaust manifolds and heavy factory catalytic converters on the C6 Corvette are designed primarily for emissions compliance and cost-effective mass production, rather than optimal volumetric efficiency. These factory units suffer from poor flow characteristics due to uneven runner lengths, rough internal casting flash, and abrupt collector transitions. Under heavy throttle, this creates severe exhaust backpressure, causing heat soak in the cylinder heads, limiting scavenging efficiency, and choking the true output potential of the LS2, LS3, and LS7 powerplants.

The Engineering Solution

Upgrading to these long tube headers completely transforms the exhaust dynamics of the vehicle. Constructed from TIG-welded stainless steel, they feature mandrel-bent 1 7/8-inch primary tubes that merge smoothly into massive 3.00-inch collectors. This design optimizes exhaust pulse timing and creates a powerful scavenging effect that pulls spent gases out of the combustion chamber faster. The CNC-machined 2-bolt flanges ensure a leak-free seal against the aluminum cylinder heads, preventing warpage under extreme thermal cycles. By eliminating the factory bottlenecks, these headers instantly increase high-flow air capacity, resulting in proven gains of 10-15 horsepower and torque, while radically deepening the exhaust note.
