Increase your X15’s performance with ITI’s high-flow 3-piece exhaust manifold, engineered to improve exhaust flow by up to 20% over the factory design. Manufactured from high-silicon molybdenum cast iron, it provides superior high-temperature strength, oxidation resistance, dimensional stability, and resistance to thermal-fatigue cracking.
ITI’s Triple-Seal Piston Ring technology improves sealing between all three manifold sections while allowing easier installation and removal compared with rigid or interference-style joints. The design also accommodates thermal expansion and contraction, helping reduce stress across the manifold during repeated heat cycles.
If selected, the manifold includes the bellows kit for a complete installation. An optional thermal coating is also available and recommended for maximum durability, improved heat retention, and long-term reliability. A pre-machined EGT port with removable plug is included, making EGT sensor installation quick and easy whenever needed.
