They are the smog pump lines. You can plug them up, but you should remove the smog pump as well.

It feeds air into the exhaust to help it be cleaner blah blah blah you get the idea. Use a piece of heater hose w/ two hose clamps to reattach. It isn't going to hurt your performance to hook it up.

I say hook it up.

Or you could go ghetto and just plug it up with an old lug nut like I did :D



For whatever reason, if you DON'T plan to hook it back up, at least plug it, better yet, run a short belt, or even BETTER get rid of all the smog **** :D

If you don't plug it it makes an annoying sputtering put put put put sound :mad:

You'll have to pinch off the tube on your new H-Pipe as well if you don't use it.

Yup! Its just an air line from the smog pump. For some unknown reason, mine came off the other day and I thought I had a header leak or a hole in a muffler or something, but after looking, the hose had come off the H-pipe. Not only did it sound awful, (tick tick tick putt putt putt) but the car lost some power.

Anyway, once I get off my lazy butt, ill go grab some rubber tubbing and clap it back together.
