I need a quiet catalytic converter.
I just got a Code 67 on my 1996 LS. I'm assuming I should replace my O2 sensors and my catalytic converter since they're 13 years and 203,000 miles old. If anyone thinks there might be other problems please let me know, I'm going off of searches I've made to these forums about code 67.
My question(if I'm right to think it's time to replace these items) is what kind of cat should I get? I should state here that I no longer race and I am much more interested in making this car legal and quite than I am in making it fast. That being said I wont turn down free horsepower if it comes in the form of a street legal and quiet hi-flow cat. Any suggestions? I've been looking at the Magnaflow since I trust the name but has anyone had any experience with these?
