yes, I agree with the craftsmanship of the Megan set up (mid pipes, axle backs, and y-pipe) if I understand the OP correctly, you were just interested in the mid pipes?? and keeping your stock mufflers?? I believe you will get better flow from the y-pipe into the mid pipe and possibly get just a little 'tad' of sound, but performance wise, depending on the piping from the stock muffler -- possibly 2" or 2 1/4"s -- you will now be going from a larger diameter(from the mid pipes = 2 1/2") to a smaller pipe leading to the muffler you may lose some hp....again, I'm not too sure of the M45's tubing, since I have the M35. if you are keeping the stock mufflers, you may want to consider enlarging the pipe (small section) from the muffler to the mid pipe extension pipes...just a thought.
But, if you were to go with the Megan mid pipe AND axle backs, you would definately get more flow and power...the sound will be good since you are keeping your factory resonator. as far as your intake, a K&N drop in will work just fine...
