I was thinking about changing the headers to some DC headers, but i wanted to know what i can expect? would it be worth it? what would be the pros and cons of doing this to an automatic transmission? Should i get anything with the headers to improve performance?

Mods im sorry if this is in the wrong forum, i searched for headers and all i got was a bunch of f/s listings.

 

Well searching for the plural version of the word definitely would yield poor results, seeing as you only have 1 header.

Plus, if you would have checked the FAQ's, you would have already found out that there is nearly 0 benefit from having an aftermarket header.
