Even though the C7 Corvette is right around the corner, that’s not stopping companies like Pfadt Engineering [1] from releasing new products for your C6 Corvette! Originally only available for the Z06, Pfadt has just announced fitments on LS2, LS3, and LS9 ‘Vette engines for their TRI-Y headers.
Official Release:
Pfadt Tri-Y Headers For C6
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. Take a look at the highlights below.
