Resonator size

[Bigcat24]

Anyone know the inlet and outlet size for the two rear resonators? I already put in the Flowmaster bolt in muffler but want to get rid of the puffing sound from the 2 rear resonators by replacing them with straight pipe. I don’t plan to spend the $ on the Flowmaster resonator delete kit unless someone has a compelling reason why. Thanks in advance!

I have Flowmasters super 44’s and got rid of the resonators. Definitely louder and that puffing sound is of course gone. So to me it’s worth it. Just remember it does make your exhaust louder. At least for me it did. I had them cut off the resonators and straight pipe it follow by the stock tips. Sounds so much better.
