Description

The VelocityTitan exhaust header provides an effective performance upgrade by giving each cylinder its own dedicated exhaust path. By reducing back pressure and minimizing exhaust interference, this manifold allows for potential increases in horsepower and torque when paired with high-performance components like cold air intakes and cat-back exhaust systems. This stainless steel unit features an inlet size of 1.75" x 1.25" (oval) and an outlet size of 2.375". It is compatible with 1.6L and 1.8L engines, including direct bolt-on installation for 1994-2001 Acura Integra GSR/Type-R models. Modification is required for 1999-2000 Honda Civic Si and 1993-1997 Honda Del Sol V-TEC applications. Important fitment caveats apply: this header will not bolt to an OEM catalytic converter. A 2.5" inlet catalytic converter or test pipe is required for successful installation. Professional installation is recommended, and users must account for the required 2.5" diameter compatibility to complete the setup.
