03 Altima Y-Pipe and SE-R Mufflers Upgrade 

I have a 2003 Nissan Altima 3.5 and just recently replaced my Y-Pipe and replaced my original muffler with SE-R mufflers. The shop that did the work also removed the 3rd converter next to the Y-Pipe which I did not really need. I kept the OEM resonator, however I am considering a magnaflow or borla resonator.
