What should I do?

I have a 2012 Ram 1500 V8. The truck is true dual with an X pipe no muffler. I still have the catalytic converters. After the catalytic converters the pipe is 2 1/2 however,  the cat back exhaust pipe is 2 inches.  My question is should I make everything 2 1/2  or keep it the same?

    Keep it the same.  Hope you do not get noise tickets.

    At wide open throttle, where do you need more power?

    What type of driving are you doing where dumping several hundred bucks for a couple horsepower yeilds a return on investment.

    Smaller exhaust pipes boost low RPM torque. Bigger pipes increase horsepower. Which one do you need? If you tow, you want torque.
