Exhaust Manifolds and Headers for Leak Repair, Better Flow, and Performance Builds An exhaust manifold is one of the first and most heat-exposed parts in your exhaust system. It collects exhaust gases from the cylinder head and routes them toward the exhaust pipe, catalytic converter path, or turbocharger. When the manifold is cracked, warped, rusted, or leaking, it can cause ticking noises, exhaust smell, reduced throttle response, poor turbo response, and lower engine efficiency. SPELAB offers exhaust manifolds and exhaust headers for drivers who need reliable replacement parts, leak repair solutions, or performance-focused exhaust upgrades. This collection includes OE-style replacement manifolds, stainless steel headers, diesel truck manifold options, Jeep repair manifolds, turbo exhaust headers, and classic performance applications. Because exhaust manifold fitment can vary by engine, side, material, and hardware, choosing the right part is important. Before ordering, always confirm your year, make, model, engine, mounting side, material type, and whether gaskets, bolts, studs, or clamps are included.
