I apologize for another header/exhaust thread but i have not found anything saying these will match up. I ordered these today Header and am looking for a Corsa Sport Exhaust, will they match up to the sport one Corsa ???? Once again i apologize for another thread. But i have been searching this for the last week. Also should i ceramic coat the headers? I live near Edmonton, Alberta and would sooner do it right the first time. I figure i should put this all in one would it be worth while to put a 160 t-stat in? The winters do get cold here and it is my DD. I will be getting a custom tune but before i install anything i would like to send all the mods that will be on it when i get the tune so i dont have to keep sending the PCM in. You guys all seem very knowledgable and have alot of experience. Thanks in advance and sorry for the long blurb.
