Rob22 Posted May 6, 2012 Posted May 6, 2012 Started to notice a little rattle during the week which sounded to me like a heat shield. I thought id take a look today to try and sort it out. However before I got the chance I got a fault code on the dash yesterday. Plugged in the reader and it said O2 sensor for bank 2. I cleared the code and it hasn't come back. Under the car today the heat shields look fine but I can get a rattle by thumping the cat pretty hard. With the fault code coming on I'm wondering if this may be the a problem inside the cat itself rather than a heat shield. Anyone able to offer any insight? Rob Quote
Neilp Posted May 6, 2012 Posted May 6, 2012 I have standard cats that I may be willing to sell. They have only done around 20k miles before I removed them and fitted with decats. Theyre from a 2006 revup car with de engine Quote
Rob22 Posted May 18, 2012 Author Posted May 18, 2012 Got this sorted, the culprit was a fracture in the cat housing. The bracket that attaches to the support had broken away. All fixed and I can now enjoy the noise of my nismo back box again thanks to NeilP for the parts Quote
narcotix Posted May 19, 2012 Posted May 19, 2012 I had the same issue on my cats .. I just used a jubliee clip and tightened the housing onto the cat ... No more rattle! Quote
