Any good sources to purchase new headers for my 575sci's........ I will be inspecting mine this spring and may have to replace with brand new headers some time soon.......twin application so I will need two sets.....

CMI

I'd give my "opinion" but other OSO members will just rip me and tell me my opinion doesnt count,, bcuz i have no experience and that i should be in school.... So hopefully you get alot of good options...

Good luck..!!!

CMI wont let you buy direct , always had good luck going thru Teague .... C'mon BIG Bobs gotta eat too.

For what it's worth, take them off and bring it long island propellors. I've heard only good things from them. Could save you a couple thousand bucks. Gave them my cmi's last month. Saw them finish up a big hp set of headers and the finished product was amazing.

I'd strongly consider going with the SM manifolds. Cheaper, close on the power, and wont have to worry about it again.

SM mainfolds? whats that?

SM = STAINLESS MARINE
do a google search i thought you knew this stuff

Do a search kid... I'll even tell you SM stands for "Stainless Marine".

Please report back to all of us what you found and any insight YOU might have on the subject.

You beat me to it.
