Do the Ford flex pipes leak air? I got my entire exhaust on and headers on, when I drive and accelerate I can hear what sounds to be air leaking from under me. It�s very quite but I don�t know where it could be coming from besides the flex.

Any ideas/suggestions?

Thanks

did u replace the gaskets from the flex pipe? i had to replace the flex pipe last summer, and didn't get the gaskets and had a little air leak. once i put in both gaskets leak was gone.

Try feeling for air. If it's a small leak you may not feel it but a large one yes.


And yes, flex pipes can leak. I had one in my old GTI that leaked bad on the flex part.

Check your EGR tube! After I did mine It started leaking about 2 days later I had to pull it back off of the header & retighten but it still leaks!
