Resonator and secondary cat delete. You could also get tips for looks. Those are the cheap options then there are full exhaust which cost from 600-1200+

you can also upgrade your exhaust! AA is a great example.

About maybe less lol exhaust is mostly for sound

I got 5whp and 10tq from muffler delete and K&N drop in. In reality that most likely means the car was performing better than it was the day I dyno'd stock due to variations in conditions (same dyno, just different day).

As 330xtrai said, its sound and weight savings. That's about it.

Muffler delete, paid $140 for it. Sounds great to me.

Cat/res delete. will actually add HP

2ndary cat delete gives a nice burble sound too with the PE which isnt too different from a res delete. If I were you I would take it to a shop and ask to have the resonator and both secondary cats removed and straight pipes welded in their place
