I’m pretty new to the platform, but i’m finally thinking about doing some stuff under the hood. I did some research and created this list of upgrades i’d want to do since getting it boosted is out of the question.

INTAKE
3 inch cold air intake (sound+throttle response)
or
K&N box filter (cost effective)

EXHAUST
1: 2.5-inch true dual exhaust with an X-pipe (cat-back)

2: High flow cats (combo with headers)
3: Headers** (Tune ASAP)

TUNE:
professional ecu tune/ecutek
(note: tune can improve transmission.)
z1 tune link

just wondering if you guys have a good suggestions for brands. any knowledge i might need to know would also be much appreciated too, as this is my first time ever modding a car. Also, sorry if i sound green lol I’m trying to learn though.
