Universal X-Pipe Crossover Kit
  • Piping Diameter: 3 in.
  • Material: 409 Stainless Steel
  • Overall Length: 37.75 in.

    This universal X-pipe kit crosses the two sides of a dual exhaust system ahead of the mufflers, using the crossover to balance pulses between banks for a torque gain and a deeper, more unique exhaust note than a traditional H-pipe. Mandrel-bent 409 stainless steel tubing keeps the crossover free of the kinks that rob flow in a press-bent design.

    Universal X-Pipe Crossover Kit Specifications:

    • Piping Diameter: 3 in.
    • Bend Type: Mandrel.
    • Material: 409 Stainless Steel.
    • Overall Length: 37.75 in.
    • Overall Width: 16 in.
    • Overall Height: 9.5 in.
    • Fitment Type: Universal (cutting and welding into the existing system required).

    Emissions Note:

  • Not All Mid-Pipes Are Created Equal

    Flowmaster's Scavenger Mid-Pipe Kits are designed to mount ahead of the mufflers in place of a traditional restrictive factory mid-pipes. The D-Port technology allows the exhaust pulse to create a low-pressure area that helps pull, or scavenge, from the paired set of tubes. This produces a significant torque improvement and a more free-flowing exhaust system. Well-suited for modified GM, Ford and Mopar cars, maintaining the classic Flowmaster sound.
