328 exhaust setup



so the first "box" is the cat converter right? a second one is resonator and the 3rd one is the muffler right?

Can I do this:

y adapter from the headers, after the angle put a high flow cat, and then a high flow resonator and then a magnaflow muffler?

what is the in pipes size form the header and what is the biggest pipe size I can go with coming out of the Y adapter? I read it somewhere is 2.25 in from the 2 pipes connecting to the header, and the outlet size is 3 inches right?

cats are in your headers. just remove the back resonator and muffler. if you get catless headers it will make your car very loud
