blinkimgone04 Posted December 28, 2008 Report Posted December 28, 2008 I'm trying to order a new muffler online but not sure of the size I need! I tried to find the diameter of my exhaust by using the Circumference.. C = PI x D D = C (~8.7 inches) / PI (3.14) D = 2.75 inches Is this the right size to order a new muffler? Please help!! Thx !
