Developed to meet the needs of even the most heavily modified GTO applications, these Long Tube Headers employ 1 3/4" primaries and 3" collectors to provide huge power increases throughout the rpm range. Team them with one of the LoudMouth® or PowerFlo® cat-backs to create a fully optimized exhaust system.

Race-proven on SLP's 575-hp ZL-402 development car!
