Factory exhaust with a Nismo Y Pipe? I've seen a couple guys runnin around in G's and Z's w/the factory exhaust but it sounds almost like a nismo setup. Did they upgrade the Y pipe and Cats? If anyone on here has experience with this, please share. I have a full Nismo catback but i like the look of the factory muffler more than the Nismo.

I'm basically looking for a setup that sounds almost like the Nismo but w/the factory muffler. Thanks

 

never seen this set up
