The 2006-2013 Corvette Z06 is one heck of a machine, there’s no denying that! Our friends over at Pfadt Racing take the 505 HP LS7 one step further, by creating these amazing Tri-Y long-tube headers. You can see as much as 40 additional horsepower and 40 lb-ft. of torque to the rear tires with these headers fitted to your LS7. Get more details below!
Pfadt Tri-Y Corvette Headers For C6 Z06
Pfadt Race Engineering is taking its expertise in manufacturing well-engineered high performance suspension components and implementing it in a new breakthrough Tri-Y header design for C6 Corvettes! Immediately setting itself out from the pack, the headers feature what you have come to expect from Pfadt: motorsports design technology in a street-performance Corvette product.
The Pfadt design takes proper exhaust flow to a new level by pairing non-adjacent cylinders together to create a super-scavenging effect with the 4-into-2-into-1 (Tri-Y) construction. In this system, the exhaust flow from individual cylinder pulses are optimized to suck air into the combustion chamber from the intake. This creates a much more efficient power curve that results in a greater amount of usable torque (called torque under the curve) in the mid-range, while not sacrificing any top-end power for peak numbers.
