Assuming the rest of the car is stock, the Only thing you're missing is a high flow airfilter.

I'd recommend An upgrade rear motor mount (rmm) as well.

A catless downpipe will throw a DTC code unless you have it tuned out or run a defouler.

If your state requires emissions testing, you may run into problems depending on what type of test(s) they perform.
