i have a magnaflow catback part number on summit- MagnaFlow 15684

my question is, can i take out the muffler and replace it with an slp resonator? i want loud and im not really about to hack up my exhaust for cutouts. has anyone done this?

 

You'd only have one tip that way. I also think that cat back would have two 2.5'' exits, where as the SLP would need to be 3'' on both sides. Good luck and let us know what you decide to do.
