I've owned a 2010 Maxima for about 1.5 years. I want to start making performance upgrades. I've been told the best place to start is an intake and new high performance exhaust. Others mentioned the above at the same time as a "chip". I'm very green when it comes to this. I'd love it if someone on this forum could give me some sound advice on this. I also want to upgrade brakes and suspension. Keep in my that this is my daily driver and I'm starting a job as road rep soon, and will be driving 400-1000 miles per week, so I can't take a huge hit in fuel economy or make the ride too stiff. Just looking to make it a little faster, sound better, handle tighter.
