Exhaust system question fro 94 RT/10

[Roland L-Ocala FL]

Is the stock exhaust system 2 1/2" diameter pipes through the mufflers? I keep seeing some posts as 3" while others mention 2 1/2" size, what's right for a stock exhaust in case I want to put in less restrictive mufflers?

They're 2 1/2. You can go to 3 inch but that's not the stock size. I replaced my stock mufflers and cats with Jon B's latest setup and kept the standard size pipes and am very pleased.
