CAST INLETS AND OUTLETS:
Our competitors solution to utilizing larger catalysts necessitates a harsh outlet angle, resulting in exhausts gasses exiting in a very inefficient manner. Fabspeed Motorsport USA CAD designed investment cast inlet and CAD outlet sections were Computer Designed for the smoothest and highest maximum possible flow both in and out for maximum exhaust velocity and power! ONLY Fabspeed Motorsport with over 25 years of Street and Race Competition experience goes to this EXTREME to maximize power and sports car sound!
Keeping heat in the exhaust maintains the maximum velocity of exhaust gasses, allowing the turbos to spool faster while ensuring maximum power is extracted through increased thermodynamic efficiency and flow. Fabspeed thermal blankets are rated to 1800 degrees. T321L Stainless steel mesh over a 321L stainless steel inner liner covering ceramic insulation makes direct contact with the downpipes.
