Need some muffler help guys!

not sure what part number it is but i know it isn't the 12588. physical size is the same but it is a 3"dual in/3.5" single out

True i was just going by the size forgot about the inlets and outlets.

for most applications the 12588 works the best...only in a very few such as mine would I go this big..

for the record.. 18'' magnaflow si/do with LT's and no cats sounds VERRY good.. mellow if you keep steady throttle, but barks when you get on it
