when i was changing my tranny fluid i noticed some different lines coming out of my cat. do these have to do with emissions? if so...if i were to remove them along with anything else that has to do with emissions control would my stock ecu go crazy? would there be any sort of hp gains? also...i purchased my car with the pettit intake already installed.... is the 3rd small filter even necessary or does it have to do with emissions also? if i'm way off on this post please let me know and just disregard thanks

 

i'm just gonna start taking **** off and finding out for myself
