HAMMER_VR6 0 Posted January 1, 2011 Report Share Posted January 1, 2011 Last few days have noticed my exhaust blowing and sounding crap.Had my car on a ramp today and it is blowing from the factory CAT, The fumes were coming from a threaded hole on the right hand side, were the cat joins the system. Does it just need a blanking plug or is there meant to be a sensor in there.Oxygen sensor is at the top front of CAT and still attached. Link to post Share on other sites
cabrioman 6 Posted January 1, 2011 Report Share Posted January 1, 2011 some of them have a blanking plug in there so try getting one to block it back up failing that get it welded up Link to post Share on other sites
HAMMER_VR6 0 Posted January 1, 2011 Author Report Share Posted January 1, 2011 ok thats cool i was hoping it was just a blank. Otherwise i had lost the sensor. I did remove a rather rusty 17mm bolt off the suspect area but it was totally mangled so didnt no what was missing. Guess ill need a genuine blank plug Link to post Share on other sites
