Hi guys and gals. Since the winter is approaching and the heat is being used more in the car I've noticed that unless I push the recirculate air button I can smell exhaust fumes in the car. I'm thinking there is probably an exhaust leak coming from my eurocharged headers. I have tried looking for a leak but I just cant see down in there very well. Could it be something else besides the headers is my main question before I start trying to tackle resealing the headers. tia

You can use that old trick of spraying soapy water on the exhaust while the car is running and looking for bubbles forming. I would bet it's your headers though.

Your only other alternative would be to take into a shop, have them raise the car, and use a probe to sniff out exhaust leaks.
