need good hi flow cat suggestion
So Im going to be putting the thundermuff exhaust on today and had a question. My last exhaust was a n1 ripoff with a test pipe cat. Even tho my o2 sensor is plugged into the cat, its throwing CEL. My question: should I get a regular hi flow cat...and who makes a good one? Whats the difference between a hi flow cat and a test pipe?
thanks! MUCH appreciated i wanted to learn about this before i tore the old exhaust off

RE: need good hi flow cat suggestion
I am using a universal fit Magnaflow hi flow... I like it.... I throw a CEL about 2 times a week but only for a couple minutes when the car is cold. I dont know why. The code isnt even applicable to my car so I am even more confused!
