Flowmaster #17228 Question?
Im researching getting exhaust for my brothers 91 Z28 G92 and have found the American Thunder system, for dual cats(17228). But, flowmaster's website lists it as a 3" system with dual 2.5" outlets whereas summit lists it as a 2.5" system. Which one is it?

I have these on my 84Z28. Still in the process of putting them on with a dual cat setup from a 91 GTA I think. I'd assume there the 3" system. They measured 3" OD and 2-7/8" ID.
