Any aftermarket catless header will be better than a cated one.
If you want to make more power, as stated, I haven't tried a good aftermarket 4:2:1, maybe a ACE or JDL would give me more? Maybe?
Honestly, I would decat the OEM and used the money saved for dyno time with a Ecutek tuning solution.
After you remove the restrictions from the cats, it all about a "good" tuners ability and having a play for a while.
Later if you need another 5hp or torque you can look at dropping $1-2k on it.
Have a look at fluid dynamics IRT header and exhaust design.
If you want the rumble, a UEL header will give you that, it will be louder with the 2.25" OEM front pipe punched out and stock exhaust, a 2.5" catless exhaust with a resonator and rear box will be loud to the point of being annoying.
I cannot really comment on sound as that is too subjective.
Me, I just like to have the most power, with the least noise.
OEM exhaust parts are cheap, sometimes free, so playing around costs next to nothing.
Have fun

I started thinking about replacing the header when I saw this deal:

$1050 CAD for OFT + OFH (approx $780 USD)
I like the OFT because I can always revert back to stock if I need to go in for warranty work.
