The Tri-Y Headers is designed with an emphasis on maximum low and mid range torque, while making ample horsepower throughout the RPM range. The 4:2:1 Tri-Y headers design makes it the ideal choice for trucks, tow-rigs, RV's and most street applications. The collector design makes this header one of Doug's most efficient, which means you'll see improvements both on the dyno and at the pump.
A Doug Thorley Headers original design, the 4:2:1 collector specification on the Tri-Y Headers is engineered to match your engine's firing order and thereby maximize exhaust scavenging - the complete expulsion of gasses on the exhaust stroke. The Tri-Y design creates more usable power and torque than any other headers design, making it the headers of choice for enthusiasts who want the most bang for their buck.
