Speed Engineering 2" Longtube Headers & X-Pipe Full Kit for 2014–2017 Chevrolet SS Sedan 6.0 LS2/6.2L LS3 applications.
This complete bolt-on system replaces the restrictive factory exhaust manifolds and mid-pipes with free-flowing 304 stainless longtubes and a 3" off-road X-pipe that connects directly to the existing axle-back location. Designed for maximum horsepower gains, aggressive exhaust tone, and long-lasting durability.
Speed Engineering Chevrolet SS Sedan longtube headers are built from premium 304 stainless steel and combine outstanding quality, performance, and affordability. Each system is mandrel bent, TIG welded, and features natural stainless construction for exceptional fitment and strength. Dyno-proven for performance and reliability, these headers deliver impressive flow and sound. You won’t find a better-fitting, quality-built, budget-friendly header setup for your Chevrolet SS Sedan.
⚠️ Note: Rear (downstream) O₂ sensors are not used. A check-engine light for catalyst efficiency will appear and must be disabled via PCM tuning.
