    Put a set of Hard-Krome stepped headers and there 4 inch exhaust system in last week.
    VORTAXX™ TRUE DUAL EXHAUST

    Features
    4” diameter outer muffler constructed using RES-TEC™ (Reduced Exhaust Sound TEChnology)
    RES-TEC muffler cartridges significantly reduce both hi- and low-frequency sound waves
    Stepped header design tapers from 1.75” diameter to 1.875” diameter to 2” diameter; outer pipe measures 2.75” diameter
    Features patented True Doublewall Construction (U.S. Patent # 6,908,980) and CNC-machined billet end caps on front and rear of muffler body
    Doublewall construction includes a 1 3/4” inner pipe which holds most of the heat generated from the exhaust, and a full-length large-diameter outer pipe which acts as a heat shield.

    They are a bit louder than my V&H ovals where, was hoping for a little less noise. Don't know if I will like the black and chrome tips. May have to buy the chrome tips.

    Bike is all stock except for the race tuner, air cleaner and pipes. They did a dyno calibration on it and it is putting out 92 HP and 112 torque. If I want more I need to change cams and port the heads out.
