Full Tilt Performance has proven to be leaders in the truck parts industry. Known for their high-quality craftsmanship and high-performance designs, Full Tilt Performance puts extensive research and innovation into every product they create.
OEM exhaust manifolds are notorious for leaking, cracking, and restricting airflow. Over time, repeated heat cycles cause the manifold to warp and crack, leading to exhaust leaks that reduce performance and efficiency. Surprisingly, OEM manifolds are also not optimized for airflow, creating unnecessary backpressure that limits engine power and fuel economy. If you're looking for a more durable, high-flow solution, upgrading to this Full Tilt Performance exhaust manifold is the best way to improve reliability, power, and overall engine efficiency.
This exhaust manifold is engineered with the highest-quality metal blend, specifically designed to withstand extreme heat cycles without warping or cracking. It is also thicker and more durable than OEM, eliminating common leak and failure issues. The manifold is precision-engineered to optimize airflow, ensuring the engine gets the proper exhaust flow needed for faster turbo spool-up and improved performance. To further enhance efficiency and longevity, each manifold is ceramic coated, which helps retain heat for better turbo response while also protecting surrounding components from excessive heat exposure.
Extensive dyno testing and real-world road testing have shown that upgrading from a healthy OEM manifold to a Full Tilt Performance manifold can result in around a 0.25 MPG fuel savings. In cases where the existing manifold is sooted, leaking, or severely restricted, the improvement can be even greater. Over time, the fuel savings alone can pay for the manifold, making it a smart investment for both performance and cost efficiency.
