Tegiwa Exhaust Manifold Header Civic Integra B-Series

TEGIWA Race Exhaust Manifold. Constructed from 304 grade Stainless steel. These headers feature the popular 4-2-1 design with a true 2.5" collector, CNC mill-cut flanges, and robotic rotation purge TIG welding. Being a 4-2-1 configuration means it has excellent clearance and ultimately your header wont get beat up on speed bumps. It has been proven as being one of the best 'off the shelf' headers available. We dyno'd it back to back against an OEM 98spec JDM header and it made 7.2bhp & 0.9ft/lbs. Against a Civic VTI/ UK Integra manifold you will see gains of 12bhp and 7ft/lbs torque. Weighing just 5.9kg its not only boosts your engines power but dramatically reduces your vehicles kerb weight -the OEM 98spec JDM header weighs 8.2kg and the cast 96spec header weighs 15kg. To install this manifold you will need to ensure you have a 2.5" cat. Suitable for all B-series engines B16A, B16B, B18C.
