TurboGS300 Posted May 8, 2005 Share Posted May 8, 2005 I used a universal on my GS3 and it works fine! You may have to weld in a bung for the 02 sensor if it located near the cat. <_< Quote Link to comment Share on other sites More sharing options...

melhadri Posted May 8, 2005 Share Posted May 8, 2005 What year is your vehicle? How many miles do you have on it? I think there is a Federal Gov't Emmissions Program, where all Manufactures are responsible for replacing malfuctioned major emmission components, such as the Cat, free of charge. However, the car must meet a certain criteria: no older than 8 yrs old and less than 80k miles. Do a search and you may find more about this topic. I wouldnt be to thrilled with replacing the CAT, as it may cost $1k+. Hope this helps. Quote Link to comment Share on other sites More sharing options...

The Cat isn't responsible for much of the sound, the multiple silencers and mufflers do that. I had a look around and I don't seem to see a supplier for cats for GS models 1998 and up. If anyone finds an aftermarket supplier, let us know! Quote Link to comment Share on other sites More sharing options...

Contact the dealer and ask what the criteria is and take it from there. Good Luck !!! B) Quote Link to comment Share on other sites More sharing options...
