Hey guys, I got a 2017 Corolla iM. It's nice and drives smooth but needs a bit of a kick when it comes to acceleration. I was looking at the HPS shortram air intake and also wanted to pair it with a bypass valve aswell as a new exhaust kit. For the exhaust, I don't want anything just unnecessarily loud. I want something that would help with performance and even efficiency if possible. Any suggestions?

Welcome to the neighborhood!
Considering the efficiency of the Toyota air-box it's doubtful any CAI will add anything but noise to your car.
If you still decide to use one best to stay with a unit that uses a dry filter not oil coated.
An exhaust system may provide some kick but they're kind of a placebo performance boost.
The interior noise is subjective to what you can tolerate. If you can, lean towards a stainless steel system.
Next time you need tires go with something shorter it will change the effective gear ratio lower and give you a little bit better launch.

Fair enough. As for the extra boost that I{'m looking for, other than tires, anything else you would suggest?

Really not aware of anything but I haven't spent anytime looking.
