Was watching GT racing and heard a term I'm not familiar with...

[Jeff7181]

The guy said, "Most of the Corvettes in the field run closed headers..." What are closed headers?

 

[KLin]

Closed Headers or Closed Exhaust System: Refers to an exhaust system that includes mufflers; not open to the atmosphere.

From here: http://www.proracingsim.com/glossary.htm

No sh!t?

That's what I thought... but they were talking about how someone else designs the headers, and then Borla makes them. I thought they were talking about the headers only, not the full exhaust system.

It also means that the headers must also be optimized to work with a full exhaust system. Most drag cars don't use mufflers so their headers are designed to be run open.

Borla makes mufflers.

Borla makes mufflers.

And headers and complete exhaust systems and CAT's. So?
