Product Description:Satin black. The 4" muffler slowly tapers to 4 1/2" diameter at the rear. Comes with a 3" core for high flow. The frequency and perforation pattern of the muffler scatters mid-frequency sounds to provide you with a robust low tone exhaust. These Slip-On mufflers will fit with stock head pipes or CobraÂ´s head pipes. Expect improved power, especially in low and mid-range torque, right where you want it.
