2007 nissan sentra 2.0s improvment ideas?
 

I just got an 07 nissan sentra 2.0s.I realize there are very little aftermarket mods available,but people said that about hondas at one point lol.so if you have any ideas or know of any performance parts avail let me know.
so far i have ordered a fujita cai.Iam going to buy the jet maf next,and cant decide what muffler to go with? I want something thatl improve performance and provide a good sound but not the ridiculous loud crappy sound we all cant stand.so any help will be appreciated ...

I think Stillen has a catback available for the 2.0s

Engine sound is the product of the engine design / cylinder configuration.. the most cost efficient way to upgrade is to trade in your new car and add some money for something better.

lol I have a 420hp mustang so Im good to go on upgrading to a fast car.I was just looking for some ideas on how to upgrade and or make the sentra better.my other ride is a full bolt on 06 gsxr 750 so i do realize what is fast and what is a lil economical 4cyl..so any tips or parts people know of for the sentra let me know...cheers

Its already a known fact that parts for the 07+ sentra arent abundant.

i would first. upgrade the suspension.

springs and sway bars. then move on to an intake.
