Ordering headers this week and need help deciding between my two choices
I am considering:
1) Pacesetter Mid-tubes (ceramic coated) that hook up to stock catted y-pipe.
2) Mac Mid-tubes (chrome) with their ory.
Pacesetter says I could expect a 8-14rwhp gain using their headers with stock y pipe and cats on it.
Mac's webpage says that you can expect 28.4 rwhp using their headers and ory.
Questions:
1) Are these accurate expectations for both of these header systems?
2) If so are the Macs really that much better than the Pacesetters in order to get double the performance?
3) Does ceramic coating really make that much of a difference? Because if I get the Pacesetter I can afford to have them put the armor-coat coating on it, but if I get the Macs I will be getting the chrome ones not the cermac coated ones for $ reasons.
I know PS are good I just have a prob with them for some reason!LOL! Stupid I know!!!

This was a "before & after" shot I took with the left header being polished vs. the right unpolished.
No coating or chrome to worry about wearing off, and zero ground clearance loss over stock.
So far everyone is voting for the macs...anyone want to jump in and tell me if Mac is bs'ing on their site saying you can gain 28.4 rwhp using their headers and ory, or is that about right?
The only thing I can see is there is a different design for the Mac mids for the single catalytic convertor cars compared to the dual cat cars. The 28.4rwhp gain is advertised on the single cat style...I am assuming this would be the same for the dual cat style but could be wrong.
Can you run the single cat style headers on a car that was originally dual cat if you are doing an ory and deleting that stuff anyway? Or do you have to get the dual cat setup for a dual cat car regardless of whether or not the cats are present?
You can run a single cat y-pipe if you have your rear O2 sensors tuned out in the PCM. (Plus all the other benefits you get from a tune.)
Some other alternatives would be to run O2 simulators, or do an OBD1 conversion. But a tune would be your best bet.
