Speed Engineering 1-7/8" Longtube Headers & X-Pipe Full Kit for 2011–2017 Chevrolet Caprice PPV 6.0L 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 noticeable horsepower gains, aggressive exhaust tone, and long-lasting durability.
⚠️ Note: X pipe and true dual exhaust would require modifications at the axle back flanges for the installation on the Caprice application.
⚠️ Note: Rear (downstream) O₂ sensors are not used. A check-engine light for catalyst efficiency will appear and must be disabled via PCM tuning.
Speed Engineering Chevrolet Caprice longtube headers are made from high-quality 304 stainless steel for strength and corrosion resistance. Each header is mandrel bent, TIG welded, and built for precision fitment and excellent exhaust flow. Dyno proven and track tested, these headers provide outstanding performance and unbeatable value. You won’t find a better-fitting, quality-built, budget-friendly header system for your Chevrolet Caprice.
