Description
Dramatically Improves Performance. This Stainless Works 1-3/4 Inch Headers with Catted Y-Pipe is specially designed to replace the restrictive factory headers. It features a free-flowing design that utilizes mandrel-bent pipes for optimum exhaust flow that boosts power and performance. Additionally, the included Y-Pipe is compatible with the stock exhaust.
Aggressive Exhaust Note. The Stainless Works 1-3/4 Inch Headers with Catted Y-Pipe is designed to emit a race-inspired growl with moderate volume and aggressiveness. This can be combined with a separately purchased Stainless Works exhaust for the ultimate growl.
High-Flow Catalytic Converters. This kit comes with a set of cats that are less restrictive than the factory catalytic converters. The high-flow design help in maintaining the increased airflow for improved horsepower and torque.
Durable T-304 Stainless Steel Construction. The 1-3/4 Inch Headers with Catted Y-Pipe is made from high-grade stainless steel to ensure toughness and durability. The precise CNC laser-cut flanges and mandrel-bent tubes ensure a precise fit for straightforward installation.
No Tune Required. The 1-3/4 Inch Headers with Catted Y-Pipe is precision designed to work without any retune. However, a retune after installation is recommended to ensure the best possible performance from the Silverado.
Not CARB Certified. The 1-3/4 Inch Headers with Catted Y-Pipe is not CARB certified. It is not intended for use in California or any state that adopted California emission standards.
Application. The Stainless Works 1-3/4 Inch Headers with Catted Y-Pipe is designed to fit 2003 to 2006 2WD 4.8L and 5.3L Chevrolet Silverado models.
