hi guys i am new here. i just wanted to ask a few questions hope you can help out.

first question...

is there a real racing chip for the yaris? not those ebay ones but a legit one like from superchips or something like that. i did find this item but i am not sure about it.

what do you guys think about it?

second question...

i have headers and a cat back exhaust. but my mid pipe is stock. where i am there are no real regulations needing cats or anything like that. i want to get more HP. do you think it is a good idea to remove the cat and replace with a pipe but i would want to leave the mufler in the mid pipe alone. i just want to remove my cat.

hope you can help! thanks!
