  • 31143 - FlowTech Shorty Truck/SUV Headers is rated 1.0 out of 5 by 1.
    Rated 1 out of 5 by from Doesn't fit properly The drivers side fit fine but the passenger side collector flange was off drasticlly. Ha to cut the flange off my down pipe and rotate it about 20 degrees and change the angle to make the flange bolt up and seal.
