Test pipes or Hiflow Cats???
HFC vs Test Pipes
If you don't have to worry about emissions, I'd get the Test Pipes. I have just converted from HF Cats after about 25K miles since I had one collapse on me. Now I have Test Pipes. Sounds about the same, can smell a little exhaust at lights but at WOT sounds great and now no worries about anything collapsing.
I recommend the fast intentions test pipes or HF cats, I've only heard good about them, you should check them out, i think in the classified there is a sale going on but not sure how long it lasts
