I have some questions regarding Headers... I currently live in CA and want to get headers for my car.. I noticed there are a lot of variations and wanted to get a better understanding of them


First question is, What are connection pipes? Do you need them in order to install them to your car?

Second, What are catted connection pipes? Will these pipes prevent me from having a CEL??

Third, what are Green catted connection pipes? They are almost double the price of a regular Header so wanted to know their purpose.

Thanks guys. Looking forward to hear your feedback
