The 4.3L V6 in an S-Series truck is exhaust limited by its cast manifolds, and a shorty header set is the change that fits without touching the rest of the system. Primaries are 1-1/2 in., sized for the V6 rather than borrowed from a V8 set, and the kit retains the factory emissions plumbing so the truck stays street legal.

Edelbrock 68543 Tubular Exhaust System Details:

• Steel construction with Ti-Tech C-105 titanium satin coating.

• No welding required for installation and factory emissions equipment is retained.
• Do not apply thermal wrap or extra coatings, which voids the warranty. High temperature plug wires are recommended.
