Hello,
It is my first post here. I have 2001 I30, and in my country it is called Maxima and I have one 2002. I'm here in US for studying : )

Anyway, I have questions about exhaust and rims.

I found 2007 G35 rims, they are wider in rear, the rims look like this:



So, are they fit on my I30? without making and mod? And do you think they will look nice?



Exhaust, I'm looking to change my I30 exhaust, but I need your help. I'm looking for a cat back, could you please provide me with some brands that fit on my I30? And do you recommend me to make it two dual instead of single? If so, would that be expensive? would that give more power that the single? would that increase the fuel efficiency? Please provide me and give me an advice.


Thanks in advance.
