I know that the SE exhaust is 2.25 and the R/T exhaust is 2.5, but is that in ID measurment or an OD measurment? I would just check it myself, but the kids have run off with the tape measure again. Thanks in advance.

I don't know if this helps but just something I found.
Mufflers come in standard pipe sizes and are measure I.D. (inside diameter) while pipe sizes are measured O.D. (outside). A 2" muffler inlet is made to slip over a 2" pipe. The most common pipe/muffler sizes are: 1-1/2", 1-3/4", 2.00", 2-1/4", 2-1/2" and 3.00". Diesel trucks will usually have 3-1/2" to 4.00" stock sized pipe.
It was on.

You're right, stupid question.

I'm just kidding! There's no such thing as a stupid question...
but then again, there was my ex. Eh, forget it. :disgust:
