Preferably I would just like a new muffler instead of whole exhaust system. Any one have any good suggestions for a muffler? I checked out some magnaflow mufflers. Also help if you guys gave me the inlet diameter and the muffler type. Thanks!

 

The Nissan Maxima stock muffler is nice, and quiet. Get that 1.

 

Depends on your preferences, I'm actually working on some custom setup, but if you want more sound, you can go by removing the silencer and letting the two stock mufflers, if you want even more sound you can look for some catbacks, you can look up for the sound you prefer on youtube, or change just the mufflers for some flowmaster's or magnaflow's, just look for examples, the stock size is 2.25".

 

oem is good.
