Hey guys, first questions is where can I get a header and a manifold for 1.8L ST?
2nd, What effects will changing out my fuel filter and oil filter have?
3rd, I have a 2 1/4 piping from cat-back. Anyway, im wondering what the difference is if the pipe is strait from the cat to back? And what the difference is from my car having it strait then at the end it swirls around my suspension or something.

1- Ebay.
2- Your car should run better and you may gain back some hp, but not likely. Do it anyways, it's routine maintance.
3- if it's straight, it's a better flow path. The shorter the path, and the less bends, the better. But on a Celica, it doesn't really matter. There won't be a power difference.
Have a good one. And thanks for not asking about body kits and the such.
