When upgrading your engine, begin by replacing the exhaust manifold. Cylinder exhaust flows into the manifold (an engine component), then travels through the exhaust pipe, muffler or silencers, and exits via the tailpipe. Our high-performance stainless steel manifold replaces the restrictive factory version, enhancing exhaust flow and significantly increasing power and torque across the entire RPM range.\u003cbr\u003e2. Exhaust headers are metal tubes that connect the engine’s cylinder head to the exhaust system, efficiently directing exhaust gases away from the engine. They attach to the cylinder head using a flange and merge into a larger collector, which connects to the rest of the exhaust system via bolts or welding.\u003cbr\u003e3. Crafted from CNC-machined T-304 stainless steel pipes and precision TIG-welded flanges, these headers are built for exceptional strength and durability.\u003cbr\u003e4. Designed for hassle-free installation, the headers feature pre-welded hangers for a direct bolt-on fit—no modifications needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping (UNITED STATES):\u003c\/strong\u003e\u003cbr\u003eHandling Time: within 24 hours\u003cbr\u003eShipping Time: 3-5 days\u003cbr\u003eTracking info will be emailed to you once the order has been shipped.
