i THINK that my o/r xpipe may be leaking from the passenger side header. WHen the pipe was installed, it was checked for leaks, and they said that there was none. they told me to listen too, and i didnt think i heard any either. Last week, it started to sound like there may be a leak. it only happens when i give the car some gas, like to pass someone etc. but, it sound like an airy sound coming from the right side (i hear it through the floor). THere also sounds like there is a ticking sound coming from there too when i give it some gas. Dont know if its a leak, or just the sound of the xpipe. Thanks in advance!
