Pipe Sizing - O.D. vs I.D.?
Is exhaust pipe measured by O.D., and muffler inlet/outlet measured by I.D.? (So the pipe will slide inside the muffler ends?).
Another question: Is anything gained by installing a larger inlet/outlet muffler to a smaller diameter pipe, and using reducers to match everything up? An example would be using a 2 1/2 inch muffler on a 2 1/4 inch exhaust pipe.....
Thanks.

Thanks Mike, that's sort of what I thought, but I needed confirmation. I'm getting ready to order a muffler, and want to make sure it's going to fit.
Nick88, my first thought was that larger muffler inlet/outlets would act like an expansion chamber, and change the exhaust tone. Like Mike says, I doubt if it would make any difference. In fact, it may cause some unwanted resonance......?
