Special Features

  • Performance Upgrade – Designed by Certified Automotive Experts, these 304 stainless steel long tube headers feature 1-5/8" primaries and 2-1/2" collectors, optimizing exhaust flow to increase horsepower and torque in the mid to high RPM range. Perfect for drivers seeking reliable performance and improved throttle response.
  • Durable Construction – Built with fully mandrel-bent 16-gauge stainless steel tubes, these headers provide consistent strength and smooth airflow. The polished finish adds corrosion resistance while delivering a premium look that outlasts standard exhaust components under demanding conditions.
  • Precision Fitment – CNC laser-cut 5/16" thick flanges are flattened by hydraulic press for a secure, leak-free seal. Designed specifically for Chevy and GMC C1500, C2500, K1500, and K2500 trucks (1988–1998), ensuring professional-grade installation and long-term durability. They also fit the 1999-2000 Classic (carryover body style) but will not fit 1999 and newer new body style trucks.
  • Superior Craftsmanship – TIG-welded joints reinforce strength, prevent cracking, and improve wear resistance even under high temperatures. Certified Automotive Experts ensures each header meets strict performance and durability standards, making them ideal for both enthusiasts and daily drivers.
