Also not doing the headers. Doesn't sound work it.

On so with the test pipes, do I understand this correctly?

1. Most hp gains are straight test pipes but loudest?
2. Second highest gains are resonated test pipes? Benefit being not as loud but still more hp than hfc?
3. Hfc are still upgrade to replacing cat but least amount of hp?

1. Yes
2. The resonator does not affect HP gains, only sound/rasp.
3. Yes, depending on which brand you go with and what size cell they use (100,200,300), they will have different impacts on HP and smell.

Also, check in your state/county to see if it is legal to not run cats. If you have to do emissions testing, you will have to swap them for the stock cats prior to your inspection. Some HFCs have passed I believe, but I can't remember which ones.
