hey guys are the high flow cats worth the money when used with an exhaust system? I have a cherry bomb that dumps out the side of my truck right now...

 

I have a magnaflow highflow cat on mine, and I noticed a good difference. (atleast from my old rattley cat)

 

i herd that some HF cats can throw codes every now and then.. supposably has to do with our o2s, somthing about how our 02s can only read so much, and when it is increase over that amount it thows codes off and on... cant remeber what the guy called it when i talked to him.. ****! Damn Brain Farts.
