Currently have stock manifolds but want longtubes. I have the mikes power pipe and 2nd cat delete that I would like to keep bc it sounds so good. I know it'll be louder but hope it keeps the same kind of sound.. Do I just need to buy the headers by themselves and they'll fit with the rest of my exhaust or what do I need? Also I have E85 so what injectors should I bump up to when I do the headers. Thanks for the help!

Should bolt right up.

I installed agency headers to my stock exhaust with the secondary cats cut out.

Over this past summer I installed HFC to tame that monstrous exhaust note.

I think it would depend on the header you choose. If you're utilizing your factory exhaust you'd need to have a flange welded onto the header/exhaust.

Correct me if I'm wrong...

Edit: Unless you're using an aftermarket mid pipe.

yea you should be fine. And for injectors you need 550cc when you go headers and e85 (eurocharged and advanced pro dynamics recommendations)
