I'm planning on installing a complete exhaust system next month. My cat is clogged, and I can't drive the car. I was gonna just throw on a straight pipe for a few weeks, and was wondering what to do with the AIR line/fitting that is supposed to come from the cat?

Does that make sense?

 

You could get the MAC off road pipe that goes in place of the cat...it has a AIR tube in the pipe....or you could just crimp the ends of it....thats what i did for a week or two when mine clogged...make sure its completely sealed...but easily re0opened.....good luck
