Best Mods for My 2015 Nissan Maxima - Help!

I'm looking to upgrade my daily driver's performance and features. I have a 2015 Nissan Maxima with a V6 engine. Are there any reliable mods that can improve its power output, handling, or add convenience features? Specifically interested in exhaust systems, intake upgrades, suspension enhancements, and interior modifications. Any recommendations are greatly appreciated!
