Will these headers fit the stock set up, and what would the horsepower/torque gains be more or less???

Rob

  • These headers will not fit the stock setup, they require the use of the dynatech shorty midpipe and a full 3" catback exhaust system. The horsepower and torque would increase with the install of these up to 40 increase on both hp and torque.
