Speed Engineering 1-7/8" Longtube Headers & X-Pipe Full Kit for 1997–2004 Chevrolet C5 Corvette applications equipped with LS1 and LS6 engines.
This complete bolt-on system replaces the restrictive factory exhaust manifolds and catalytic mid-pipes with free-flowing stainless Longtube headers and a 3" off-road X-pipe that connects directly to the factory cat-back location. Designed to deliver strong horsepower and torque gains, improved throttle response, and a deeper, more aggressive exhaust tone while maintaining excellent durability and fitment.
⚠️ Note: Rear (downstream) O₂ sensors are not used. A catalyst efficiency check-engine light will occur and must be disabled through PCM tuning.

• (1) Pair of stainless steel 1-7/8" Longtube Headers
• (1) 3" Off-Road X-Pipe / Connection Pipe
• (1) Set zinc-coated header bolts (or stainless ARP bolts if selected)

Plug wires and heat sleeves can be added to the kit if selected.
