Greetings everyone.
I fell in love with the sound from Gpeterson119's Flowmaster Super 44 muffler. I sent a message to a local muffler guy about getting this one installed: https://www.holley.com/products/exha.../parts/9424472. I believe that it is the right one, as it is 2.25 in and out, as well as having the dual outlet. I want to keep my stock tips as well. However, he got back to me and said that the only muffler he could install for me was this one: https://www.holley.com/products/exha.../parts/9525454. Not only is it 2.5 in and out, but it also has dual inlets. From the pictures I've seen, our cars have 1 2.2.5 inlet, and 2 2.25 outlets, correct? I'm not sure why the one I sent him originally would not work. Or maybe I am wrong, and if so, please do tell me what I have gotten mixed up. Thank you everyone for your help.

PS: Gpeterson119, if you see this, please tell me the part number for your Flowmaster! Thanks!
