pretty sure the stock pipe is 2&1/2, not 3. why dont u go to that page , type in what year, etc. & it will say if it fits. if u want loud or bada$$ as u put it, a 40 is the one.
what u want is 2.5 center in, and 2.5 offset out. i myself did 3 inches both in and out but i had custom pipes too, but i also have a 4.o v6 tho, super 44 offroad series.
I have a Magnaflow 12256. Smaller then oem so you'll have to add pipe but the offset is a perfect fit. Deep and throaty sound on the V8. Not super loud and no drone.
