4-2-1 Header

The DC Sports 4-2-1 Header is engineered to maximize your engine's output, delivering the most power and torque available. Its race-inspired 4-2-1 design, CAD-rendered for precision, emphasizes low and mid-range power ideal for street or strip applications. The header is constructed from durable steel with a ceramic coating for enhanced longevity and performance. This one-piece header design not only improves ground clearance but also reduces overall weight by eliminating middle flanges, making it significantly lighter than stock and two-piece systems. The use of CNC mandrel bends and robotically-welded fittings ensures a perfect fit, while CNC-machined and threaded flanges contribute to optimal system tuning for power gains across the entire RPM range. Equal length primary piping further refines the exhaust gas flow for increased power. Professional installation is recommended to ensure proper fitment and performance. This header is specifically designed to fit the 2000-2004 Toyota Celica. If your vehicle has aftermarket or custom altered parts, it is the installer's responsibility to verify fitment.
