3″ Taller Polished Downturned Sport Tube Header
The all polished 3″ taller CMI Sport Tubes are a superior long tube header designed for both racing or virtually any high-performance application. For big-block applications where maximum scavenging and horsepower are required, CMI Sport Tube headers deliver peak performance and power from naturally aspirated engines that generate more than one horsepower per cubic inch of displacement. These particular headers are commonly used in staggered forward engine applications.
