Hooker has quickly become the leader in engine swaps and we are excited to announce new products for 1994-2004 Mustangs. Our Engine Swap exhaust systems are designed to offer the best-available ground clearance and wide rear tire compatibility. These 304 and 409 stainless steel exhaust systems feature turn downs right after the mufflers to accommodate greater sized rear wheels/tires than with full-length tailpipes.

  • Incorporates use of merged-X crossover for maximum power with minimized drone
  • Turn down system permits use of greater sized rear wheels/tires than with full-length tailpipes
  • Compatible with the stock OE or Hooker SN95 Mustang transmission crossmembers
  • Lightweight, 18-gauge, 304 stainless steel construction maximizing strength and durability
  • All hardware included
  • Quality welds for strength, longevity and good looks
  • Utilizes OEM mounting points for factory-like fitment
