Been looking around, and finally pulled the trigger on the NISMO catback exhaust for my 2010 3.5. Leeparts is selling them for $773 + shipping which comes to about $950. I managed to find a Nissan dealer in CT selling them for only $702.60

This is slightly cheaper than from Lee and I believe they also allow you to pickup from the dealer to save from shipping.
Total for me came to $790 shipped, which is much cheaper from anywhere else I can find with shipping included.
It's Bruce Bennett Nissan in Danbury, CT. Just thought I share this with fellow members on the fence about the exhaust.
