Ok ive done my searching and havent found a definitive answer. Are you required to remove the rats nest and emissions when installing a new header (anything but the thermal reactor)?

 

No, you don't HAVE to remove anything when you add a header or remove the cat/thermal reactor. The Air pump feeds into the exhaust via a "tube", but you can just cap that line.

If you added an after market intake set up (carb and manifold) than you would remove all the rats nest / emission, because they wouldn't work together.

But emissions equipment is corny (unless your state checks emissions) remove them anyways, even if you're staying stock

 

Awesome thanks

 

cap the air pump tube?..i just removed it...its not bad is it?

 

Well I suppose you don't have to cap it, but I would think debris could some how work it's way into it some how...even thou it's blowing out.
