Performance World 423240 Chevrolet LS Cast Iron Header Manifolds

Our cast iron exhaust manifolds are a block hugging design to fit various applications including engine swaps. Smooth short design aids in exhaust flow and allows for maximum ground clearance. Cast iron provides a leak-free and quieter option from traditional headers. Fits all 1998-2016 LS except LS7 and LS9. Not compatible with 2004-2006 GTO starters and bellhousings.
