LT1 / LT4 Headers ExtReme Full Length

$1,499.00

Speedtech Performance headers have been custom designed specifically for ’68-74 LT1 or LT4 powered Novas using our Speedtech ExtReme subframe.

Made from 304 Stainless Steel, these big tube .065 wall CNC mandrel bent primary tubes fit perfectly without requiring dimpling for steering linkage, engine component or frame rail clearance. Their long tube design provides awesome low end torque and street performance with excellent mid and higher rpm horsepower. Add to that fantastic ground clearance that’s perfect for lowered Pro-Touring type cars and you’ve got a great combination.
