xle

I'm just curious if I am capable of modding my Corolla XLE with some Corolla S/XRS parts. I'm pretty new to the whole car world so sorry if this question seems pretty obvious to some. Right now it has 166,000 miles and a automatic transmission. Is modding it worth it at this point? If so, what...

I made a video of testing the PCS. Take a look and please give me some feedback regarding how the PCS system is supposed to work. Thanks.
