SLP 98-99 LS1 F-Body 1-3/4" Tuned/Long Tube Headers

Widely copied but never equaled, SLP's Tuned-Length Long-Tube Headers employ our patent-pending tuned-length design to optimize exhaust scavenging for phenomenal power increases. Gains of up to 41 horsepower and 58 lb.-ft. of torque are possible, depending on your application!

These headers are constructed from 409 stainless steel and feature 1-3/4" primary tubes flowing into a 3" 4-into-1 collector. They're fully compatible with all stock emissions-control equipment and use OEM flanges for a perfect fit and proper bolt retention. Includes matching Y-pipe.

NOTES:Requires Installation Kit #30054. Automatic-transmission-equipped convertibles will also require Crossbrace Kit #30055. Use with Catalytic Converters (Part #31037). Headers reduce ground clearance by approximately 1-1/2 inches. Not legal for use on pollution-controlled motor vehicles.
