Well, I've already asked the question, s how about the details. I bought my car a few months ago, and it has a header. I plan on doing some exhaust work, and I'd like to know who makes my header, how can I tell?

 

If it has an "RB" stamped on it, it's made by Racing Beat. Other than that I have no idea, but if it's not Racing Beat (most are) it's probably Pacesetter.

 

Pacesetter = horrible if you didn't already know

it was dynoed and showed a hp decrease
