Speed Engineering 1-7/8" Longtube Headers & Y-Pipe Full Kit for 1998–2002 Chevrolet Camaro and Pontiac Firebird LS1 applications.
This complete bolt-on system replaces the restrictive factory exhaust manifolds and mid-pipes with free-flowing stainless longtubes and a 3" off-road Y-pipe that connects directly to the existing cat-back location. Designed for significant horsepower gains, aggressive exhaust tone, and long-lasting durability.
⚠️ Note: Rear (downstream) O₂ sensors are not used. A check-engine light for catalyst efficiency will appear and must be disabled via PCM tuning.
