Ported headers - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Ok.... I was bored and looking around at the various bolt-on possibilities that I plan to purchase for the new Camaro. I had a question about ported headers though.... without sounding like an idiot, what exactly does it mean for the exhaust manifold to be "ported"? I know that it increases flow, but what is the difference betwen a ported header and a non-ported header?

I dont know havent heard of them. I would guess they have holes "ports" on the headers to let excess air out to reduce backpressure further or let air into the pipes to get better flow.

This, is what I've learned to love about this site. When a subject comes up, and I have no Idea what I'm, or anyone else is talking about, I look it up and learn something new and useful every day.

here's what I found, I think this is what you meant...don't know how "ported" holds any relevance though.

Wow, great find and good info.... that makes a lot of sense. I knew that "porting" the headers somehow increased exhaust flow, just wasn't sure how. That explained it perfectly.

As I now understand it...
"porting" is the process of essentially creating a larger opening and removing the bottleneck in the exhaust manifold.

Glad I could be of help.
