Hey all, just got my first G35x 2005 grey on black two days ago, loving it so far, came from an 03 altima V6.

I did have 2 concerns and was hoping someone can point me into the right direction. Been reading the forums for the last 2 days and wanted to clarify some ideas.

The previous owner put on an exhaust that is louder then my taste. I was wondering what I could get to quiet it down, a resonator? Muffler? There were large threads with so many variations that I could not ultimately decide what the best option is without spending 300$.

Also I was wondering what your thoughts were on common problematic areas I should re-evaluate on the G35x. I have read some have oil consumption issues and window motor issues. How are the sensors on these cars?

Thanks in advance!
