Stainless Steel H-Pipes
PYPES' Ford Mustang H-pipe design synchronizes the balance of the exhaust pulses from each bank of cylinders based on the firing order. This process increases velocity and scavenging from each cylinder, which frees up some low-end torque and adds a unique sound. PYPES H-Pipes are mandrel bent from 409 stainless to ensure a long life of high-flowing performance. Flanges, mounting hardware, O2 sensor bungs, clamps, and ball flares are standard features.
