dumb problem.
I plan on going FI within a few months and was wondering are these little rings from the old exhaust going to have a significant affect in any power beings that it is right at the collectors? I was thinking of bringing my car to a place and have them heat it up and take it out.
Also I was thinking about just installing 1 3/4" headers when I go to do the install, but whoever I bought the car from with the current headers did not use stainless header bolts. I am afraid of one to break off in the head, and do not want to get into that big mess. I still have plenty of time to think about all this but would like to get some imput from you guys.
Thanks for any help, John.
