I have the exact exhaust with the side pipe. I mean if you wanted to get the full cat back system you could but I think welding on a new muffler and getting some pipe work done saves money with the same effect. I can post up some pics tomorrow if you want just say what you want to see.
I would love to see how a 2011 Magnaflow exhaust with side exit look on a 2014-2015 4runner
