HOW MUCH POWER ARE LONG TUBE HEADERS WORTH? WHAT MAKES MORE POWER, 1 3/4 HEADER OR 1 7/8 HEADERS? WHICH HEADER SIZE MAKES THE MOST TORQUE? DO LONG TUBE HEADER IMPROVE LOW SPEED TORQUE? HOW CAN I ADD MORE TORQUE? HOW CAN I ADD MORE POWER TO MY LS? DO LS EXHAUST MODS WORK? CHECK OUT THIS VIDEO WHERE I COMPARED 1 3/4INCH LONGTUBE HEADERS VS 1 7/8INCH LONG TUBE HEADERS WITH TWO DIFFERENT CAMS (BTR TRUCK NORRIS AND SLOPPY BEST CAM). I ALSO TESTED THE EFFECT OF COLLECTOR LENGTH ON POWER BUT COMPARING A SHORT COLLECTOR EXTENSION VERSUS A LONG COLLECTOR WITH MUFFLERS. LOTS OF GOOD LS HEADER INFO HERE!
