I am getting a mix of answers from some people saying mid muff is at the "Y" before the two large mufflers and resonator is the mid one while others say the larger long one after the Cat is the mid muffler and replace with straight pipe and the circled one in red is rear resonator?

I have this resonator ordered but do not want to install in wrong location.

in my tsx, the red circled is the mid muffler, the one towards the center of the car, is the resonator.

so the circled one is the one usually straight piped?

The larger one is probably the mid muffler and the 1 before the mufflers is the resonator. It's too small to be a muffler.

what kind of car is it that you're talking about?
