Putting together our Steeda Stainless Steel High Flow Cat X-pipe along with Kooks Stainless Steel Super Street Shorty headers gives you a powerful combination that provides gains of 18-20 horsepower and up to 16 ft/lbs of torque at the wheels.

These gains come at a more economical cost than a full stainless steel long tube system and with an easier installation. An easier installation can also save you money if you do not intend on doing the installation yourself.

Warning: This part has been designed and is intended for off-road application only. Installation of this part on a vehicle that is driven on public roads may violate U.S. and Canadian laws and regulations.

Product Benefits

  • Matched combination
  • Provides 18-20 horsepower
