Don't worry about back pressure, you wont lose enough for it to be remotely detrimental to vehicle performance.

Which ford racing exhaust do you have? I don't know of any that are 3"

Wow, I've never heard of that setup before.

It does affect back pressure because the exhaust gasses can flow more freely and efficiently away from the motor, but it will not drop back pressure enough to effect performance. Some people are of the belief that back pressure doesn't affect motors, some believe that a slight decrease in back pressure will make the car sluggish. Then there's us realists, and we know that it is real and will affect your car but realize that fluid dynamics and internal combustion motors are so far beyond the scope of our own knowledge that we stick to the results of independent testing and don't try to oversimplify these complexities

Back pressure is never an issue, you can run open headers and be fine. exhaust gases don't follow standard fluid dynamics and no, I don't understand them anyways. Exhaust scavenging can be negatively effected by running too large a diameter tubing in the HEADERS not an issue past 18-24in after the collector

For what that ford cat back costs I'd just get the kooks cat back. You can get the entire exhaust (motor to tip) from kooks for 2400$

Apparently I'm the only person on this forum who prefers stainless works headers above all others. I must be a noob.

Kooks and stainless works are both great!! Just depends on personal opinion because either isn't really much better than the other

Ppl don't get that stainless power and stainless works are basically the same thing. Only that the stainless power set up is several hundred dollars cheaper

Catted h pipe. Had the x pipe. But it was just too raspy for my liking. Prefered the lower grumble of the h pipe
