Not another ebay header thread. Ebay headers

I've read many eBay header threads and have one very specific question that was not addressed in the many threads I read. I have heard of ceramic wrapping/coating the headers and my question is what will happen if I don't? Will I get heating issues or error codes?

No heating issues by not wrapping or coating your headers, but under hood temps will be lower if you do & it may be worth a very small amount of WHP. You will get error codes when you remove your CATS.

On a side note, wrapping your headers provides two small benefits.
1) If you run your knuckle into a wrapped header you might not get burned.
2) Wrapping provides a small amount of sound reduction.

Much appreciated, I think I'm going to go with the spark plug trick with the shark injector. Even if the shark doesn't take off the code I feel that the shark > than AA because of the higher rev limit and lower cost.

Well in terms of cost, the shark is less money and he may be on a budget. Also, there's no removing and shipping away anything. It has it's pros, but for cons you're probably referring to the quality of the tune and of course AA is better there, they do it per customer which is a more custom job and a higher quality tune. The shark is meant to be easy, quick, and have some positive effects as well. People will pay for easy and quick, this we all know.

wrapping headers can also cause them to crack and form exhaust leaks. get them coated, it doesnt cost that much
