Yes, this exhaust manifold kit is designed to permanently fix the exhaust leak that causes the common HEMI "tick". The noise is a result of broken manifold bolts and a warped factory manifold, which this kit directly addresses. — 5.7L HEMI engines are known for a design flaw where intense thermal cycling causes the original factory bolts to stretch, fatigue, and eventually break. Once a bolt fails, the manifold is no longer held tightly against the cylinder head, allowing it to warp from the heat. This creates a small gap that lets exhaust gases escape, causing the distinct ticking sound you hear, which is especially noticeable on a cold start. Our kit solves this by replacing the manifold with a thicker, high-silicon ductile iron casting that resists warping, and by including longer bolts with spacers that are specifically engineered to withstand thermal expansion without failing.
